This patchset :
- updates the Amlogic PCI bindings for G12A
- reworks the Amlogic PCIe driver to make use of the
G12a USB3+PCIe Combo PHY instead of directly writing in
the PHY register
- adds the necessary operations to the G12a USB3+PCIe Combo PHY driver
- adds the PCIe Node for G12A, G12B and SM1 SoCs
- adds the commented support for the S922X, A311D and S905D3 based
VIM3 boards.

This patchset has been tested in a A311D VIM3 using a 128Go
TS128GMTE110S NVMe PCIe module.

For indication, here is a bonnie++ run as ext4 formatted:
