gpu: nvgpu: add init_pbdma_intr_desc fifo ops

Browse Source 
Init device_fatal, channel_fatal and restartable fifo intr pbdma s/w
variables for pbdma_intr_0 interrupt masks for each GPU version separately

pbdma_intr_0 field differences for each GPU version:-
-gk20a  : bit 28 does not exists in hw
-gm20b  : bit 8(lbreq), 20(xbarconnect) and 28 do not exist in hw
-gp10b  : bit 8(lbreq), 20(xbarconnect) do not exist in hw. bit 28,
          (syncpoint_illegal) added in hw but is not being handled.
-gk20a/gm20b/gp10b
bit 24 eng_reset and bit 25 semaphore always existed in hw but never
handled
