[PATCH 0/3] soc/board: decouple SoC identification reads from firmware calls

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.
