arm64: dts: imx8-apalis: Add PCIe and SATA support

The needed drivers to support PCIe and SATA for i.MX 8QM have been
added.
Configure them for the Apalis iMX8 SoM.

The pciea and pcieb blocks each get a single PCIe lane, pciea is
available on the carrier boards while pcieb is connected to the
on module Wi-Fi/BT module.
The SATA lane is available on the carrier boards.
