Seshendra Gadagottu b2db6a8453 gpu: nvgpu: ga10b: set-up vab buffer during gpu re-init ...

During gpu re-initialization(rail gate exit/sc7 exit), vab buffers
needs to programmed in hw by writing vab buffer address to
NV_PFB_PRI_MMU_VIDMEM_ACCESS_BIT_BUFFER_LO(HI)_ADDR and
setting vab entries to NV_PFB_PRI_MMU_VIDMEM_ACCESS_BIT_BUFFER_SIZE_VAL.

For this moved nvgpu nvgpu_fb_vab_init_hal from
nvgpu_init_mm_setup_sw to nvgpu_init_mm_support.
nvgpu_init_mm_setup_sw is skipping during re-init, because
sw_ready is set during first boot.
