[0/4] Lantiq VRX200/ARX300 PCIe PHY driver

Message

Various Lantiq (now Intel) SoCs contain one or more PCIe controllers
and PHYs.
This adds a driver for the PCIe PHYs found on the Lantiq VRX200 and
ARX300 SoCs. GRX390 should also be supported as far as I can tell,
but I don't have any of these devices to further verify that.

I have tested this PCIe PHY driver with the out-of-tree PCIe controller
driver in OpenWrt: [0]

dependencies for this series:
none

patches 1-3 should go through the PHY tree
patch 4 should go through the mips tree

I am aware that this series is too late for the v5.3 development cycle.
Getting review comments is still appreciated so this can be queued early
in the v5.4 development cycle.
