[PATCH 1/1] zynqmp_power: Add ZynqMP PMU FW binary

Firmware is MIT licensed and is common to all SoC revisions. Board
specific config is built and loaded by u-boot. Built from the 2025.2
embedded software release.

This needs to be loaded for basically anything to work with the
zynqmp_power driver.

This is a large patch because of, ironically, the license file which I
have replicated wholesale from the xilinx embedded software repo, so
the patch is available as a gist here:
https://gist.githubusercontent.com/ld-cd/546a914c0a2437ba8928fa9f6d976df3/raw/fbfef284176f491fbe96594b5a1138f1ef954c2f/zynqmp_pmufw.patch

If paring it down to just what is linked into the final binary is
acceptable I can make an attempt to trace that out.

MR on gitlab is here:
