81d95456b9 gpu: nvgpu: Rename PLATFORM_ATOMIC to SYSTEM_COHERENT 
To support current and future usecases, it would be
beneficial to select the SYSTEM_COHERENT aperture explicitly.

The benefits are:
- platform atomic code is cleaned-up.
- userspace can select the SYSTEM_COHERENT aperture for any
  specific usecases.

Default big page size for all chips is 64K. So, move
gp10b_mm_get_default_big_page_size() to common file and rename as
nvgpu_gmmu_default_big_page_size().

Modify gv11b_gpu_phys_addr() to use get_iommu_bit() hal.
