Replaced ch->mmu_debug_mode_enabled with ch->mmu_debug_mode_refcnt.
If channel is enabled multiple times by userspace, then ref count is
updated accordingly. There is an expectation that enable/disable
calls are balanced for setting channel's mmu debug mode.
When unbinding the channel, decrease refcnt for the channel until it
reaches 0.
Also, removed tsg parameter from nvgpu_tsg_set_mmu_debug_mode as it
can be retrieved from ch.

This patch adds nvgpu API in linux and posix to query vpr resize.
The new API nvgpu_is_vpr_resize_enabled() is used in
nvgpu_submit_channel_gpfifo().
Previously, if non-deterministic channel has timeout disabled and
GPU cannot railgate on some platform, then channel doesn't power ref
count and results in video freeze. To resolve non-determinstic channel
job tracking needs to be enabled if vpr resize is supported or if GPU
can railgate.

For safety build, nvgpu driver should enter SW quiesce state
in case an uncorrectable error has occurred. In this state, any
activity on the GPU should be prevented, without powering off the GPU.
Also, a minimal set of operations should be used to enter SW quiesce
state.
Entering SW quiesce state does the following:
- set sw_quiesce_pending: when this flag is set, interrupt
handlers exit after masking interrupts. This should help mitigate
an interrupt storm.
- wake up thread to complete quiescing.
The thread performs the following:
- set NVGPU_DRIVER_IS_DYING to prevent allocation of new resources
- disable interrupts
- disable fifo scheduling
- preempt all runlists
- set error notifier for all active channels
Note: for channels with usermode submit enabled, userspace can
still ring doorbell, but this will not trigger any work on
engines since fifo scheduling is disabled.

- Alignment a's check will be bypassed when ALIGN_MASK is directly
