Physmap supports minimal PM since commit 0bc448b49e8a017e ("mtd: maps:
physmap: Add minimal Runtime PM support"), so support it also when used
in DT configurations.

Tested with a Renesas Genmai board (RZ/A1). Passes 'dt_binding_check'
and 'dtbs_check'. Supersedes my original approach "[RFC PATCH 0/4] ARM:
dts: renesas: mtd-rom has no clock and power domain":
