[PATCH] riscv: dts: microchip: add pac1934 power-monitor to icicle

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

The binding for this landed in v6.9, add the description. In the
off-chance that there were people carrying local patches for this based
on the driver shipped on the Microchip website (or vendor kernel) both
the binding and sysfs filenames changed during upstreaming.

I thought I send this out last week, but I could not find the patch on
either lore or patchwork when I went to apply it today, so I must not
have...
