- 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.

Changes added to support "rmmod nvgpu" in dgpu simulation after gpu
poweron.
nvgpu_engine-wait_for_idle got stuck in busy mode for nvdec and nvec
engines in simulation as simulation doesnt support timeout.
These engines are not valid engines in nvgpu engine list.
Add nvgpu_engine_check_valid_id before checking engine status.
Simulation crash on accessing 0xb81604 top interrupt register.
Add func_priv_cpu_intr_top__size_1_v() function to get the supported
size than using default MAX_INTR_TOP_REGS.
nvlink is not supprted in dgpu simulation. Avoid warning for
-ENODEV return.
Avoid register read following gpu power off completion.

Rename __nvgpu_set_enabled() to nvgpu_set_enabled(). The original
double underscore was present to indicate that this function is a
function with potentially unintended side effects (enabling a feature
has wide ranging impact).
To not lose this documentation a comment was added to convey that this
function must be used with care.

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

In the current code, gk20a.h includes io.h which gets directly included
in a lot of other files. io.h contains methods which uses a struct
gk20a as a parameter leading to a circular dependency between io.h
and gk20a.h. This can be mitigated by removing io.h from gk20a.h as
part of larger effort to moving gk20a.h to nvgpu/gk20a.h
