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.

Moved gv11b_detect_ecc_enabled_units function
from gv11b.c to gr_gv11b.c, as this is being
used only in gr_gv11b file.
In order to avoid GR code touching fuse registers,
as it need to include fuse HW headers in GR code,
introduced two fuse HALs which are being called
from GR code. is_opt_ecc_enable for checking
whether ecc enable bit is set in fuse register
and is_opt_feature_overide_disable for checking
whether feature override disable bit is set in
fuse register.
Initialized fuse HAL functions for chips that
make use of those HAL functions.

Add NVGPU_IOCTL_CHANNEL_RESCHEDULE_RUNLIST ioctl to reschedule runlist,
and optionally check host and FECS status to preempt pending load of
context not belonging to the calling channel on GR engine during context
switch.
This should be called immediately after a submit to decrease worst case
submit to start latency for high interleave channel.
There is less than 0.002% chance that the ioctl blocks up to couple
miliseconds due to race condition of FECS status changing while being read.
For GV11B it will always preempt pending load of unwanted context since
there is no chance that ioctl blocks due to race condition.
Also fix bug with host reschedule for multiple runlists which needs to
write both runlist registers.

Add new user API NVGPU_IOCTL_CHANNEL_GET_USER_SYNCPOINT which will expose
per-channel allocated syncpoint to user space
API will also return current value of the syncpoint
On supported platforms, this API will also return a RW semaphore address
(corresponding to syncpoint shim) to user space
Add new characteristics flag NVGPU_GPU_FLAGS_SUPPORT_USER_SYNCPOINT to indicate
support for this new API
Add new flag NVGPU_SUPPORT_USER_SYNCPOINT for use of core driver
Set this flag for GV11B and GP10B for now
Add a new API (*syncpt_address) in struct gk20a_channel_sync to get GPU_VA
address of a syncpoint
Add new API nvgpu_nvhost_syncpt_read_maxval() which will read and return MAX
value of syncpoint
