Deepak Nibade afa31cdd8c gpu: nvgpu: add support for L3 cache allocation of buffers ...

Add gv11b implementation of gpu_phys_addr() that checks the t19x
GMMU attributes struct to determine if L3 allocation should be
enabled. If L3 alloc is enabled then a special physical address
bit is set.

Add flag NVGPU_AS_MAP_BUFFER_FLAGS_L3_ALLOC to struct
nvgpu_as_map_buffer_ex_args so that User space can add a hint to
allocate buffer in L3 cache
