Make the GPU bind and rebind operations work when the driver
is idle. This required two changes.
1. Reset the GPU before doing SW init for PCI GPUs. This clears
the SW state which may be stale in the case of a rebind attempt.
2. Cleanup the interrupt enable/disables. Firstly there was one
place where nvgpu would accidentally disable the stalling
interrupt twice when the stalling interrupt and non-stalling
interrupt are the same. Secondly make sure when exiting nvgpu
that the interrupt enable/disables are balanced. Leaving the
interrupt in the -1 disable state means that next time the
driver runs interrupts never quite get enabled.

Add a full GPU reset function to the XVE block. This allows
the driver to reset the GPU (except the XVE and XP interfaces)
to clear the GPU's state.
This is necessary for the GPU rebind to work. The state of the
GPU needs to be cleared before the new driver instance can work.

Handle possible asynchronous GPU driver shutdown more gracefully.
This occurs when the GPU disappears from the PCI bus, for example,
if it overheats or detects an over current event.
Also add a preprocessor check to make sure that the
gk20a_channel_cancel_pending_sema_waits()
is always defined. In some builds CONFIG_SYNC is disabled but the
gk20a_remove_support() code does not check for this.

In many helper functions like gk20a_readl() the code assumed that
the GPU is present and registers and available. However, during
GPU shutdown this may not be the case.
In theory the driver should not be accessing GPU registers during
GPU shutdown (since shutdown is triggered by GPU registers being
unavailable) but these changes handle any missed cases where this
may happen.
This goes for GPU device access as well. Many parts of the code
assume that if the struct gk20a is valid, the the GPU dev must be
there are well. This isn't always the case, it seems.

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.

Check if the GPU is present after each register read. If the a register
read returns 0xffffffff then it's possible the GPU has fallen off the
bus for some reason or another. However, to confirm that a register read
is due to a dead GPU vs just a 0xffffffff being returned by happenstance
the chip ID register is read which should never return 0xffffffff. If
that read returns 0xffffffff as well then certainly the GPU is dead.

Add HAL interface for TSG open, which is intended to
be called from the exisiting gk20a_tsg_open function.
The tsg_open entryoint is only implemented for vgpu,
as the server needs to clear metadata when a tsg is opened.

In gk20a_scale_target(), to check for duplicate
freq requests we compare current frequency with
devfreq->previous_freq
But for very first request after boot, we have
devfreq->previous_freq set to MIN freq
And in case we evaluate new frew as MIN freq
then we skip calling postscale() and scaling
of EMC clock
This results in keeping EMC at MAX value
To fix this, add new variable last_freq in
gk20a structure.
Use this variable to store frequency value
and to compare for duplicate requests

We right now obtain pm_qos frequency requirments in
qos notifier callback gk20a_scale_qos_notify()
But now we want to limit GPU frequencies based on
frequency limited from devfreq nodes
And devfreq requirement should precede over
qos requirements
Hence, move all frequency estimation and clipping
to function gk20a_scale_target() which sets the
frequency at the end
