Process long regops lists in 4-kB fragments, overcoming the overly
low limit of 128 reg ops per IOCTL call. Bump the list limit to 1024
and report the limit in GPU characteristics.

- Added enable_mscg, mscg_enabled & mscg_stat flags,
mscg_enabled flag can be used to controll
mscg enable/disable at runtime along with mscg_stat flag.
- Added defines & interface to support ms/mclk-change/post-init-param
- Added defines for lpwr tables read from vbios.
- HAL to support post init param which is require
to setup clockgating interface in PMU & interfaces used during
mscg state machine.
- gk20a_pmu_pg_global_enable() can be called when pg support
required to enable/disable, this also checks & wait
if pstate switch is in progress till it complets
- pg_mutex to protect PG-RPPG/MSCG enable/disable

Store pending sema waits so that they can be explicitly handled when
the driver dies. If the sema_wait is freed before the pending wait is
either handled or canceled problems occur.
Internally the sync_fence_wait_async() function uses the kernel timers.
That uses a linked list of possible events. That means every so often
the kernel iterates through this list. If the list node that is in the
sync_fence_waiter struct is freed before it can be removed from the
pending timers list then the kernel timers list can be corrupted. When
the kernel then iterates through this list crashes and other related
problems can happen.

Fix below sparse warning by including nvgpu_common.h
from nvgpu_common.c
nvgpu/drivers/gpu/nvgpu/nvgpu_common.c:105:5: warning: symbol
'nvgpu_probe' was not declared. Should it be static?

Suppress error message when nvgpu tries to load VBIOS overlay, but
one is not found. This situation is normal. This is done by moving
gk20a_request_firmware() to be nvgpu generic function
nvgpu_request_firmware(), and adding a NO_WARN flag to it.
Introduce also a NO_SOC flag to suppress attempt to load firmware
from SoC specific directory in addition to the chip specific
directory. Use it for dGPU firmware files.

We have completely different versions of probe for
nvgpu and pci device
Extract out common steps into nvgpu_probe() function
and separate it out in new file nvgpu_common.c
Divide task of nvgpu_probe() into further smaller
functions
Do platform specific things (like irq handling,
memresource management, power management) only in
individual probes and then call nvgpu_probe() to
complete the common initialization
Move all debugfs initialization to common gk20a_debug_init()
This also helps to bringup all debug nodes to pci device
Pass debugfs_symlink name as a parameter to gk20a_debug_init()
This allows us to set separate debugfs symlink for nvgpu
and pci device
In case of railgating, cde and ce debugfs, check if
platform supports them or not
Copy vidmem_is_vidmem from platform to mm structure
and set it to true for pci device
Return from gk20a_scale_init() if we don't have either of
governor or qos_notifier
Fix gk20a_alloc_debugfs_init() and gk20a_secure_page_alloc()
to receive device pointer instead of platform_device
Export gk20a_railgating_debugfs_init() so that we can call
it from gk20a_debug_init()
