Previously PCI support was working because the bootloader has previously
powered up the PCI power domain.
Represent the PCI power domain, so that PCI is functional without
relying on the PCI support from the bootloader.

The Colibri default which enables USB Host power is not necessarily

Also move the regulator to the generic eval-v3 device tree since
the regulator is always on the carrier board. In the Colibri iMX7S
case the regulator is just not used. This allows to reuse the
regulator in a upcoming SKU Colibri iMX7D 1GB with eMMC.
