Currently after sending change seq RPC, nvgpu waits for a fixed time
of 20ms.
This CL replaces this with pmu_wait_message_cond, which will return
immediately after getting change seq completion event.
Also added debug fs node to get the change seq execution time.

acquisition on common clk driver's lock and nvgpu driver's locks. At
the bug, inconsistent lock ordering problem will come with one thread
gets "nvgpu lock -> clk lock" and the other thread gets "clk lock ->

Slove the latter path with one-time initializing clk_parent entry

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.
