[PATCH v2 08/10] Add interrupt registers for DPU 13.0.0

[yuanjie yang <yuanjie.yang@oss.qualcomm.com>]

From: Yuanjie Yang <yuanjie.yang@oss.qualcomm.com>

DPU version 13.0.0 introduces changes to the interrupt register
layout. Update the driver to support these modifications for
proper interrupt handling.
