Deepak Nibade 68099f8298 gpu: nvgpu: fix pbdma intr handling ...

To handle any of the pbdma interrupt, we currently write zero
to pbdma_method0 and then clear the interrupt

But this is insufficient since we cannot use same intr clear
method for all the interrupts

Hence, add intr specific routines to handle those interrupts

NV_PPBDMA_INTR_0_PBENTRY:
- fix the pb_header to have a null opcode
- fix the pbdma_method to have a valid nop

NV_PPBDMA_INTR_0_METHOD:
- fix the pbdma_method to have a valid nop

NV_PPBDMA_INTR_0_DEVICE:
- fix the pb_header to have a null opcode
- go through all pbdma_method0/1/2/3
-- if they contain host s/w methods, replace those
   methods with a valid NOP
