gpu: nvgpu: enable platform atomic feature
Support following changes related to platform atomic feature
NV_PFB_PRI_MMU_CTRL_ATOMIC_CAPABILITY_MODE to RMW MODE
NV_PFB_PRI_MMU_CTRL_ATOMIC_CAPABILITY_SYS_NCOH_MODE to L2
NV_PFB_HSHUB_NUM_ACTIVE_LTCS_HUB_SYS_ATOMIC_MODE to USE_RMW
NV_PFB_FBHUB_NUM_ACTIVE_LTCS_HUB_SYS_ATOMIC_MODE to USE_RMW
NV_PFB_FBHUB_NUM_ACTIVE_LTCS_HUB_SYS_NCOH_ATOMIC_MODE to USE_READ
In gv11b, FBHUB_NUM_ACTIVE_LTCS register has read only privilege,
so atomic mode register bits cannot be updated from kernel code.
atomic capability and atomic_sys_ncoh_mode bits are copied from
fb mmu_ctrl to gpcs_mmu_ctrl register.
new tu104 hal for fb_enable_nvlink function.
