Chip ID, PMC TAP IDCODE/VERSION/USERCODE, and the PGGS boot index are currently read either directly through MMIO or via firmware, depending on the platform and configuration. This series introduces common helper APIs with weak MMIO-based defaults for each platform and firmware-backed overrides in firmware-zynqmp.c when CONFIG_ZYNQMP_FIRMWARE is enabled. This removes firmware-specific conditionals from callers, centralizes the access mechanism, and provides a consistent interface across ZynqMP, Versal, Versal Net, and Versal Gen 2 platforms.
