Gpu boosting with input events is causing more gpu power consumption
than required. To avoid this, touch boot for gpu is disabled by not
registering gpu device for cfboost frame work. Current rail gate
entry/exit latencies are fast enough to give smooth user experience.

The current CUDA drivers have been using the regops to
directly accessing the GPU registers from user space through
the dbg node. This is a security hole and needs to be avoided.
The patch alternatively implements the similar functionality
in the kernel and provide an ioctl for it.

Add "force_reset" flag to __gk20a_do_idle()
For real world use cases like VPR resizing, we cannot wait
for railgate_delay (which is 500 mS). Hence use CAR reset
for this use case. (this is done via gk20a_do_idle() API
with force_reset = true)
Some of the test cases make use of sysfs "force_idle" and
they expect GPU to be into really railgated state and
not in CAR reset.
Hence when called from sysfs, set force_reset = false.
When global flag "force_reset_in_do_idle" is set, it will
override local flags and force CAR reset case.
This is desired in cases where railgating is not enabled
Also, set force_reset_in_do_idle = false for GM20B since
railgating has been enabled for GM20B

Fix gk20a module removal so that the driver can be correctly removed
when built as a module (CONFIG_GK20A=m). Reinsertion correctly will need
more missing deinit calls, which are not yet implemented.
This change has no effect yet on any builds since the module is built in
by the defconfig.
- don't free threaded irqs that are bound to the device
- destroy cde if it is enabled
- remove all debugfs entries recursively generated directly and by cde,
pmu, clk etc.
- free secure buffer if it exists
- remove pm_runtime_put, since it doesn't have a pairing get
- pm_runtime defines proper function stubs if it is not enabled, so
remove ifdefs and query pm_runtime_enabled()
- null and free gk20a only after all deinit has been done

In gk20a_do_idle(), we wait for platform->railgate_delay
to allow GPU to go into rail gate
But sometimes we set platform->railgate_delay = INT_MAX
to disable GPU rail gating but allow it to suspend during
low power state
Due to this, force_idle API fails (it waits for INT_MAX)
To fix this, allow forcing CAR reset instead of rail gating
with flag "force_reset_in_do_idle" defined in gk20a_platform
Set this flag for gm20b until we fix the railgate_delay

To assert reset on GPU, we store "gpu_ref" clock in
platform->clk[0] and use it to assert/deassert reset
But for gm20b, "gpu_ref" is no longer resettable.
To fix this, add two callbacks in gk20a_platform :
.reset_assert and .reset_deassert
Also, add a pointer "clk_reset" to store the clock
which needs to be reset
For gk20a specific implementation, we continue to
reset platform->clk[0]
For gm20b specific implementation, we first request
"gpu_gate" clock, store it and use it to assert reset

gk20a_get_client() and gk20a_put_client() routines are effectively dead
code. The GPU has been using pm_runtime for reference counting whether
the device should be turned on or off, and gk20a_get_client() and
gk20a_put_client() have had no positive effect on the behaviour.
In worst case these functions trigger some issues as they may trigger
code paths that should not be run. There is also a race between get/put
and busy/idle.
This patch removes the functions and reworks as_gk20a.c to correctly use
gk20a_busy()/gk20a_idle() where put/get was required.
Additionally, finalize_poweron() is moved to gk20a_busy(), similarly as
it was with gk20a_get_client(). If pm_runtime is not in use, the device
is only powered on and never off. Currently this affects vgpu power
management since it does not use pm_runtime yet.

Merge initialization code from gk20a_init_system_vm(),
gk20a_init_bar1_vm() and gk20a_vm_alloc_share() into gk20a_init_vm().
Remove redundant page size data, and move the page size fields to be
VM specific.

To help remove the nvhost dependency from nvgpu, rename ioctl defines
and structures used by nvgpu such that nvhost is replaced by nvgpu.
Duplicate some structures as needed.
Update header guards and such accordingly.

Add poll interface and control ioctls for waiting for GPU job completion
via semaphores.
Poll on a gk20a channel file waits for events from pending semaphore
interrupts (stalling) of that channel. New ioctls enable and disable the
events, and clear a single interrupt event so that next poll doesn't
wake up for it again.

Remove static variable gk20a_handle used to store pointer to
struct gk20a
Use below device tree APIs to get pointer to platform_device
and then struct gk20a
device_node = of_find_matching_node()
platform_device = of_find_device_by_node(device_node)
Also, use two versions of do_idle()/do_unidle() APIs -
one will receive void (to be used from outside GPU driver)
and another will receive platform_device (to be used within
GPU driver where it is available)

In gk20a_do_idle(), to get pointer to platform_device of gk20a,
we use bus_find_device_by_name() and pass "gk20a.0" to it
But this hard coding fails on gm20b since GPU device name
there is "gpu"
Hence to fix this add a static pointer handle "gk20a_handle"
to struct gk20a in gk20a.c
Now we can access this global pointer inside do_idle()
to get gk20a pointer and from that we can get pointer to
platform_device
