89660dbd62 gpu: nvgpu: MISRA 14.4 bitwise operation as boolean
MISRA rule 14.4 doesn't allow the usage of integer types as booleans
in the controlling expression of an if statement or an iteration
statement.

Fix violations where the result of a bitwise operation is used as a
boolean in the controlling expression of if and loop statements.

07f6739285 gpu: nvgpu: switch gk20a nonstall ops to #defines
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.

82a90170d3 gk20a: nvgpu: Remove io.h dependency from gk20a.h
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

dd739fcb03 gpu: nvgpu: Remove gk20a_dbg* functions
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.

403874fa75 gpu: nvgpu: refactor interrupt handling
JIRA: EVLR-1004

(*) 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

108c98a7d0 gpu: nvgpu: gp10b: clear ce isr before wakeup
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.
