c36752fe3d gpu: nvgpu: sim: make ring buffer independent of PAGE_SIZE
The simulator ring buffer DMA interface supports buffers of the following sizes:
4, 8, 12 and 16K. At present, it is configured to 4K and it  happens to match
with the kernel PAGE_SIZE, which is used to wrap back the GET/PUT pointers once
4K is reached. However, this is not always true; for instance, take 64K pages.
Hence, replace PAGE_SIZE with SIM_BFR_SIZE.

Introduce macro NVGPU_CPU_PAGE_SIZE which aliases to PAGE_SIZE and replace
latter with former.

6c2c4181ae gpu: nvgpu: Create hal.mm.mm for misc MM HALs
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.
