All graphics code is under CONFIG_NVGPU_GRAPHICS and all the HALs are
in non-fusa files. In order to support graphics in safety,
CONFIG_NVGPU_GRAPHICS needs to be enabled. But since most of the HALs
are in non-fusa files, this causes huge compilation problem.
Fix this by moving all graphics specific HALs used on gv11b to fusa
files. Graphics specific HALs not used on gv11b remain in non-fusa files
and need not be protected with GRAPHICS config.
Protect call to nvgpu_pmu_save_zbc() also with config
CONFIG_NVGPU_POWER_PG, since it is implemented under that config.
Delete hal/ltc/ltc_gv11b.c since sole function in this file is moved to
fusa file.
Enable nvgpu_writel_loop() in safety build since it is needed for now.
This will be revisited later once requirements are clearer.
Move below CTXSW methods under CONFIG_NVGPU_NON_FUSA for now. Safety
CTXSW ucode does not support these methods. These too will be revisited
later once requirements are clearer.

The NEXT bit can remain set for the channel if timeslice expires before
scheduler clears it. Due to this nvgpu fails TSG unbind and in turn
nvrm_gpu fails channel close. In this case, checking the channel hw
state after some time can help see NEXT bit cleared by scheduler.
Reenable the tsg and return -EAGAIN to nvrm_gpu for it to retry again.

- Modify NVGPU_GPU_IOCTL_ALLOC_AS and struct nvgpu_alloc_as_args to
accept start address and size of user memory. This allows configurable
address space allocation.
- Modify gk20a_as_alloc_share() and gk20a_vm_alloc_share() to receive
va_range_start and va_range_end values.
- gk20a_vm_alloc_share() initializes vm with low_hole = va_range_start,
and user vma size = (va_range_end - va_range_start).
- Modify nvgpu_as_alloc_space_args and nvgpu_as_free_space_args to
accept 64 bit number of pages.

APIs to set preemption modes right now have config based code to set
default preemption modes or to check if given preemption mode is valid
or not. This makes code unreadable and complex.
Rework nvgpu_gr_obj_ctx_init_ctxsw_preemption_mode() so that it checks
for initial preemption modes in the beginning. If no preemption mode is
passed while allocating context, get default preemption modes with
gops.gr.init.get_default_preemption_modes() and use them.
Rework nvgpu_gr_ctx_check_valid_preemption_mode() so that it is more
readable. Use gops.gr.init.get_supported_preemption_modes() to validate
incoming preemption modes against supported preemption modes.
Log preemption modes getting set in
nvgpu_gr_obj_ctx_set_ctxsw_preemption_mode().
Disable failing unit test. It will need rework according to new code.

Currently, we are performing obj ctx alloction for bellow classes
1. VOLTA_COMPUTE_A
2. VOLTA_DMA_COPY_A
3. VOLTA_CHANNEL_GPFIFO_A
In safety, we use Async CE but not GRCE.
So allocating obj context only for COMPUTE_A and return success(0) for
all other valid classes, after setting class in the channel struct.
