gpu: nvgpu: Implement common nvgpu_mem_rd* functions

nvgpu_mem_rd*() functions were implemented per OS. They also used
nvgpu_pramin_access_batched() and implemented a big portion of logic
for using PRAMIN in OS specific code.

Make the implementation for the functions generic. Move all PRAMIN
logic to PRAMIN and simplify the interface provided by PRAMIN.
