[PATCH] power: zynqmp: Use zynqmp_pmufw_node() from firmware

[Michal Simek]

Remove private xpm_configobject[] and use zynqmp_pmufw_node() which
provides the same functionality.
Also add debug messages for easier debugging.

Fixes: e0283cbdfd49 ("power: zynqmp: Add power domain driver for ZynqMP")
