[PATCH v2025.09.y 47/49] pmdomain: fix collision in names when registering

[Ahmad Fatoum]

From: Maud Spierings <maudspierings at gocontroll.com>

After adding the imx8m-blk-ctrl driver errors started appearing about
the genpd device already being registered.

incorperate some extra device details in the device name so this
possible collision goes away.
