From: Yuanjie Yang <yuanjie.yang@oss.qualcomm.com>
Add support for Kaanapali platform SSPP sub-blocks, which
introduce structural changes including register additions,
removals, and relocations. Add the new common and rectangle
blocks, and update register definitions and handling to
ensure compatibility with DPU v13.0.
