gpu: nvgpu: define error_notifiers in common code
All the linux specific error_notifier codes are defined in linux specific
header file <uapi/linux/nvgpu.h> and used in all the common driver
But since they are defined in linux specific file, we need to move all the
uses of those error_notifiers in linux specific code only
Hence define new error_notifiers in include/nvgpu/error_notifier.h and
use them in the common code
Add new API nvgpu_error_notifier_to_channel_notifier() to convert common
error_notifier of the form NVGPU_ERR_NOTIFIER_* to linux specific error
notifier of the form NVGPU_CHANNEL_*
Any future additions to error notifiers requires update to both the form
of error notifiers
Move all error notifier related metadata from channel_gk20a (common code)
to linux specific structure nvgpu_channel_linux
Update all accesses to this data from new structure instead of channel_gk20a
Move and rename below APIs to linux specific file and declare them
in error_notifier.h
nvgpu_set_error_notifier_locked()
nvgpu_set_error_notifier()
nvgpu_is_error_notifier_set()
Add below new API and use it in fifo_vgpu.c
nvgpu_set_error_notifier_if_empty()
Include <nvgpu/error_notifier.h> wherever new error_notifier codes are used
NVGPU-426
