ARM: imx8mq: link PCIE1 and PCIE2 power domains

Those two power domains can only be used together. The link between
the two has been dropped with the dts merge of v5.1-rc1. Fix this.

Fortunately the i.MX8MQ PCIe support will land in Linux 5.2, so we
can drop all those PCIe related local DT overrides with the next big
dts upstream sync.
