fifo_pbdma_isr is moved to fifo_intr_gk20a HAL unit and renamed to
gk20a_fifo_pbdma_isr.
The pbdma specific handling part of the function
gk20a_fifo_handle_pbdma_intr is now separated into a top level HAL
function named handle_pbdma_intr. This HAL function is implemented
for GM20B and all the other architectures use the same implementation.
handle_pbdma_intr can accept NULL values for the parameters handled and
error_notifier.
gk20a_fifo_handle_pbdma_intr is called from
gv11b_fifo_poll_pbdma_chan_status and gk20a_fifo_pbdma_isr.
The call to gk20a_fifo_handle_pbdma_intr from
gv11b_fifo_poll_pbdma_chan_status doesn't progress to recovery.
Thus, the function gk20a_fifo_handle_pbdma_intr is removed to decouple
pbdma handling from recovery. gv11b_fifo_poll_pbdma_chan_status now
directly calls the HAL handle_pbdma_intr. For gk20a_fifo_pbdma_isr,
rc_type is used to proceed to recovery by calling
gk20a_fifo_pbdma_fault_rc.
gk20a_fifo_pbdma_fault_rc is changed to public from static.

init_pbdma_intr_descs HAL ops is used to update the internal values of
the struct intr within struct fifo_gk20a. Three kinds of
intr_descriptors are filled i.e. device_fatal_0, channel_fatal_0 and
restartable_0. Breaking them into separate HALs has the advantage of
reusing the h/w headers corresponding to the device_fatal_0 as they are
same across all the architectures while those of channel_fatal_0 varies.
Another advantage is to now decouple pbdma from filling in values
within the fifo_gk20a struct. A new method gk20a_fifo_init_pbdma_descs
is constructed that initializes the above intr struct by calling the

h/w passes busy/idle straight through. fifo_engine_status registers
