a8c9c800cd gpu: nvgpu: reorganization of MC interrupts control
Previously, unit interrupt enabling/disabling and corresponding MC level
interrupt enabling/disabling was not done at the same time.
With this change, stall and nonstall interrupt for units are programmed
at MC level along with individual unit interrupts. Kept access to MC
interrupt registers through mc.intr_lock spinlock.

For doing this separated CE and GR interrupt mask functions.
mc.intr_enable is only used when there is global interrupt
control to be set. Removed mc_gp10b.c as mc_gp10b_intr_enable
is now removed. Removed following functions - mc_gv100_intr_enable,
mc_gv11b_intr_enable & intr_tu104_enable. Removed intr_pmu_unit_config
as we can use the generic unit interrupt control function.

2edf3db10a gpu: nvgpu: move mc gpu_ops out of gk20a.h and add doxygen comments for HALs
gk20a.h will include gops_mc.h to contain the mc ops definitions. Add
doxygen comments for the HAL functions that are called directly.
Also move mc_gp10b_intr_pmu_unit_config to non-fusa HAL file.

087d4d3df4 gpu: nvgpu: rmmod support in dgpu simulation
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.

Moved fb interrupt handling related code to fb intr sub-unit.

Moved following hals from fb hal to fb intr hal and renamed to:
void (*enable)(struct gk20a *g);
void (*disable)(struct gk20a *g);
void (*isr)(struct gk20a *g);

gk20a_readl/writel are replaced with nvgpu_read/writel.
Hals are populated with new function names and code is modified
to call new hals.

Moved ecc interrupt to gv11b_fb_intr_handle_ecc in a separate file:
fb_intr_ecc_gv11b.c/h
