3c556c5e95 gpu: nvgpu: gv11b: Reorg ce2 HAL initialization
Reorganize HAL initialization to remove inheritance and construct
the gpu_ops struct at compile time. This patch only covers the ce2
sub-module of the gpu_ops struct.

Perform HAL function assignments in hal_gxxxx.c through the
population of a chip-specific copy of gpu_ops.

2f6d321390 gpu: nvgpu: gv11b: add mmu fault handling
HUB reports following memory sub-system interrupts:
a) ACCESS_COUNTER_NOTIFY:
   GET != PUT for access counter notify buffer
b) ACCESS_COUNTER_ERROR:
   HUB received a NACK (BAR2 fault) when writing the
   notify buffer out to memory
c) MMU_ECC_UNCORRECTED_ERROR_NOTIFY:
   Uncorrected ECC error detected by HUB MMU
d) MMU_REPLAYABLE_FAULT_NOTIFY:
   GET != PUT for replayable fault buffer
e) MMU_REPLAYABLE_FAULT_OVERFLOW:
   Overflow when writing to the replayable fault buffer
f) MMU_NONREPLAYABLE_FAULT_NOTIFY:
   GET != PUT for non-replayable fault buffer
g) MMU_NONREPLAYABLE_FAULT_OVERFLOW:
   Overflow when writing to the non-replayable fault buffer
h) MMU_OTHER_FAULT_NOTIFY: All other fault notifications from MMU

This change is to :
-Detect other fault notify
-Copy fault info from fault snap register for other fault notify
 interrupt
-Detect and handle nonreplay/replay fault notify and fault overflow
-Copy fault info from fault buffer for nonreplay/replay fault
-Print fault info

f525ff15c4 gpu: nvgpu: gv11b: add ce interrupt handling
Added handling for below ce interrupts
-INVALID_CONFIG interrupt will be generated if a floorswept
 PCE is assigned to a valid LCE in the NV_CE_PCE2LCE_CONFIG
 registers. This is a fatal error and the LCE will have to be
 reset to get back to a working state.

-MTHD_BUFFER_FAULT interrupt will be triggered if any access to
 a method buffer during context load or save encounters a fault.
 This is a fatal interrupt and will require at least the LCE to be reset
 before operations can start again, if not the entire GPU.
