Tejal Kudav 5af8cedf05 gpu: nvgpu: Nvlink interrupt handling
Enable logging and error reporting for MIF, DLPL, and TLC blocks.
Configure the NVLIPT and IOCTRL interrupt registers to rollup
the MIF and TLC errors on the link-specific fatal line and the
DLPL interrupts on link-specific intr_a(fatal) line. Both
link_err_fatal and link_intr_a are rolled up to stall interrupt line.
In the handling ISR, clear the interrupt status registers and print
an error.
Move the interrupt handling HAL code to /common/hal.
