[PATCH v2] arm64: versal: Add SelectMAP boot mode identification

[Polak, Leszek]

The SelectMAP configuration interface provides an 8-bit, 16-bit or
32-bit bidirectional data bus interface to the Versal FPGA
configuration logic that can be used for both configuration and
readback.

A connected microcontoller to the SelectMAP interface can load boot
image with bitstream, TF-A (ARM Trusted Firmware) and U-Boot.

This commit adds the missing identification of the SelectMAP mode.
