- moved reg fields to gk20a - added os abstract register accessor in nvgpu/io.h - defined linux register access abstract implementation - hook up with posix. posix implementation of the register accessor uses the high 4 bit of address to identify register apertures then call the according callbacks. It helps to unify code across OSes.
