soc_detection() and soc_name_decode() read the PMC_TAP version/idcode registers and decode the platform. This is SoC information rather than board policy, and a firmware interface could provide it instead, so it does not belong in board code. Move both functions, together with the shared platform_id and platform_version state, into arch/arm/mach-versal2 where they still override the weak stubs in the Xilinx common board code. The board file drops the now unused linux/bitfield.h include.
