ufs: amd-versal2: Use raw read/write for SLCR/CACHE registers

2025-04-16T11:42:06Z

Update the firmware driver UFS APIs zynqmp_pm_ufs_* to directly read/write to the pmc_iou_slcr and efuse_cache registers. Replace these raw reads/writes with the xilinx_pm_request() API with the correct arguments once the PM related changes are done.
