Fix MISRA rule 10.1 violations involving gk20a_nonstall_ops
enums by replacing them with with corresponding #defines.
Because these values can be used in expressions that require
unsigned values (e.g. bitwise OR) we cannot use enums.
The g->ce2.isr_nonstall() function was previously returning an
int that was a combination of gk20a_nonstall_ops enum bits which
led to the violations.

In the current code, gk20a.h includes io.h which gets directly included
in a lot of other files. io.h contains methods which uses a struct
gk20a as a parameter leading to a circular dependency between io.h
and gk20a.h. This can be mitigated by removing io.h from gk20a.h as
part of larger effort to moving gk20a.h to nvgpu/gk20a.h

Switch all logging to nvgpu_log*(). gk20a_dbg* macros are
intentionally left there because of use from other repositories.
Because the new functions do not work without a pointer to struct
gk20a, and piping it just for logging is excessive, some log messages
are deleted.

Reorganize HAL initialization to remove inheritance and construct
the gpu_ops struct at compile time. This patch only covers the ce2
sub-module of the gpu_ops struct.
Perform HAL function assignments in hal_gxxxx.c through the
population of a chip-specific copy of gpu_ops.

(*) Refactor the non-stalling interrupt path to execute clear on the
top half, so on dGPU case processing of stalling interrupts does not
block non-stalling one.
(*) Use a worker thread to do semaphore wakeups and allow batching of
the non-stalling operations.
(*) Fix a bug where some gpus will not properly track the completion
of interrupts, preventing safe driver unloads

Move the gp10b HW headers to a new directory specially for them:
include/nvgpu/hw/gp10b
And change the code to include like so:
#include <nvgpu/hw/gp10b/hw_fb_gp10b.h>
This is part of the process to restructure the nvgpu driver.

In gp10b_ce_nonstall_isr(), we trigger a semaphore wakeup.
Currently, we clear the interrupt status register after the
wakeup is complete. There is potential for an interrupt to
come in while the wake-up operation is in progress, and it
is possible that:
1) We miss processing the interrupt in that ISR iteration AND
2) We clear the interrupt status register anyways
This change clears the status register before triggering wakeup,
so the interrupt will properly re-fire.
