This adds support for Synopsys DesignWare XPCS in net subsystem and integrates it into stmmac.
At 1/8, we start by removing the limitation of stmmac selftests that needed a PHY to pass all the tests.
Then at 2/8 and 3/8 we add and use some new helpers in PHYLINK so that we can simplify some code in stmmac and possible other drivers.
At 4/8, we fallback to dev_fwnode() so that PCI based setups wich may not have CONFIG_OF can still use FW node.
We proceed by doing changes in PHYLINK in order to support XPCS: At 5/8 we add some missing speeds that USXGMII supports and at 6/8 we do the most important change to support XPCS that allows to configure MAC and PCS withouht having any PHY neither SFP attached.
Support for XPCS is finally introduced at 7/8, along with the usage of it in stmmac driver at 8/8.
