E.g. switch driver is currently bundled in mtk ethernet driver and using different devicetree structure than linux dsa driver. We have to separate it before we can use it on r2pro. But this will take some time...also pcie(-phy) does not have a driver yet,so before adding dead code i dropped these parts for now.

pcie(-phy) should have a working driver for rk3568 as of v2023.10-rc2,
and is extended to support PCIe bifurcation with the following series:
