acc65f6e84 gpu: nvgpu: bug: move nvgpu_do_assert_print() into assert.c 
There was a header file circular dependency that was preventing
including some files. For example, for utils.h to include safe_ops.h
would include bug.h which included log.h which included bitops.h which
included utils.h. To break this loop, the macro nvgpu_do_assert_print()
into a function in a new file assert.c. With this change, log.h is no
longer required in bug.h.

This change also required adding a few includes in C files that were
picking up definitions through the chain above.

97762279b7 gpu: nvgpu: make nvgpu_init_mutex return void 
Make the nvgpu_init_mutex function return void.
In linux case, this doesn't affect anything since mutex_init
returns void.
For posix, we assert() and die if pthread_mutex_init fails.

This alleviates the need to error inject for _every_
nvgpu_mutex_init function in the driver.

939e85d35f gpu: nvgpu: add locked cond APIs for posix 
locked cond APIs are better suited when we have to check/set multiple
conditions before doing wait/signal. This should be preferred for qnx as
we can avoid unnecessary atomics.

9467646a87 gpu: nvgpu: nvgpu_cond_signal to return void 
MISRA Rule-17.7 requires the return value of all functions to be used.
Fix is either to use the return value or change the function to return
void. This patch changes nvgpu_cond_signal and nvgpu_cond_signal_interruptible
to return void since no callers were using the return value.
