This change switches nvgpu_nvhost_syncpt_is_expired_ext()
to return a bool instead of an int to remove advisory rule
MISRA 10.5 violations.
MISRA 10.5 states that the value of an expression should not be
cast to an inappropriate essential type.

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.

This reverts commit 98dca979d6.
The original commit was reverted because there was an issue
where commit "include: uapi: move nvhost user-interface headers" in
linux-nvidia repo caused DLA UMD driver to be exposed of including
kernel headers directly.
Since then, DLA UMD driver has been fixed to use headers from
user-space code. And hence restore this change and commit
"include: uapi: move nvhost user-interface headers" in linux-nvidia
repo.

Nvgpu uses many ways to check if sync points are enabled. The four
ways used to be:
platform->has_syncpoints
g->has_syncpoints
nvgpu_is_enabled(g, NVPGU_HAS_SYNCPOINTS)
gk20a_platform_has_syncpoints()
This patch standardizes all usage to now be nvgpu_has_syncpoints()
which is based on gk20a_platform_has_syncpoints() - just renamed to
be general to nvgpu.
All usage of the other forms have now been consolidated. However,
under the hood nvgpu_has_syncpoints() does check the is_enabled
flag. This flag is now set where g->has_syncpoints used to be set
based on the platform data.
The basic dependency chain is this:
nvgpu_has_syncpoints -> NVGPU_HAS_SYNCPOINTS ->
platform->has_syncpoints
However, note: there are several places where syncpoints can be
disabled if some other driver initialization fails (for ex. host1x).
Also note that nvgpu_has_syncpoints() also considers a disable
variable set by debugfs.

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
