gpu: nvgpu: Abstract IO aperture accessors

Browse Source 
Add abstraction of IO aperture accessors. Add new functions
gk20a_io_exists() and gk20a_io_valid_reg() to remove dependencies to
aperture fields from common code.

Implement Linux version of the abstraction by moving gk20a_readl()
and gk20a_writel() to new Linux specific io.c. Move the fields
defining IO aperture to nvgpu_os_linux.

Add t19x specific IO aperture initialization functions and add t19x
specific section to nvgpu_os_linux.
