[RFC PATCH 4/4] ARM: dts: imx6qdl: Add PU power-domain information to gpc node

The PGC that is part of GPC controls isolation and power sequencing of the
PU power domain. The power domain will be handled by the generic pm domain
framework and needs a phandle to the PU regulator to turn off power when
the domain is disabled.
