- 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.

tegra_get_chip_id is going to be deprecated soon and this patch removes
calls to it. Chip-ID is already read via DT and call to
tegra_get_chip_id() can be avoided by adding metadata to store the
Chip-ID information in struct gk20a_platform.

Instead of just the base address of the main register range, store
(also) the base address of usermode area. All regs may not be always
available; on vgpu guests we have only the usermode regs.
Store the usermode addr we get from a platform resource directly in
gv11b_vgpu_probe() for vgpu. In that case the main reg addr is unset.
The base address is computed in gk20a_pm_finalize_poweron() for native
environments; when the reg addr is read from a resource, the chip is
still unknown and as such the HAL op for reading the usermode base
offset is unavailable.

1) Update header path of gk20a.h files present in os/
to <nvgpu/gk20a.h>
2) os_fence_android_sema.c indirectly was dependent on gk20a.h via
semaphore.h. So, added #include <nvgpu/gk20a.h> in
os_fence_android_sema.c and replaced the header with forward
declaration of struct gk20a in semaphore.h

Move OS agnostic parts of vgpu clk code out of os/linux specific
path. This includes implementation sending rpc commands to
RM Server. Move Linux specific vgpu clk code to platform vgpu files
keeping it consistent with native implementation.
