drivers: net: stmmac: reworking the PCS code.
The 3.xx and 4.xx synopsys gmacs have a very similar PCS embedded module and they share almost the same registers: for example: AN_Control, AN_Status, AN_Advertisement, AN_Link_Partner_Ability, AN_Expansion, TBI_Extended_Status. Just the RGMII/SMII Control/Status register differs. So This patch aims to reorganize and enhance the PCS support. It removes the existent support from the dwmac1000/dwmac4_core.c moving basic PCS functions inside a new file called: stmmac_pcs.h. The patch also reviews the available APIs to be better shared among different hardware and easily enhanced to support new features.
