Fix the following MISRA rule violations in bitops unit,
MISRA Rule 10.1
MISRA Rule 10.3
MISRA Rule 10.4
MISRA Rule 11.8
MISRA Rule 21.2
Introduce nvgpu specific functions for bitops and bitmap operations
with unsigned integer as parameter for offset. OS specific type
conversions and handling of these inerfaces are taken care in the
respective OS files.

Hal API g->ops.gr.halt_pipe() is defined in unsafe unit hal.gr.gr
It is called from safe unit, and it calls into API
g->ops.gr.falcon.ctrl_ctxsw() which is also safe
Hence get rid of unsafe API g->ops.gr.halt_pipe().
Caller now directly calls hal.gr.falcon API to halt pipe

debug mode for a given context.
Added gr.set_mmu_debug_mode HAL to change NV_PGPC_PRI_MMU_DEBUG_CTRL
for a given channel. HAL implementation for native case is
gm20b_gr_set_mmu_debug_mode. It internally uses regops, which directly
writes to the register if the context is resident, or writes to
gr context otherwise.
Added NVGPU_SUPPORT_SET_CTX_MMU_DEBUG_MODE to enable the feature.
NV_PGPC_PRI_MMU_DEBUG_CTRL has to be context switched in FECS ucode,
so the feature is only enabled on TU104 for now.

There are many miscellaneous HALs for various MM related functionality.
This patch aims to migrate all the remaining MM code from the <chip>/
mm_<chip>.[ch] files in HAL files under hal/.
Much of this is fairly straightforward copy/paste and updates to the
HAL init files.
The exception to that is the move of the left over gv11b MMU fault
handling code in mm_gv11b.c. Having both a hal/mm/mm/mm_gv11b.c and
a gv11b/mm_gv11b.c file causes tmake to choke so the gv11b/mm_gv11b.c
file was moved to gv11b/mmu_fault_gv11b.c. This will be cleaned up in
a subsequent patch.
