generic: replace mtk_sgmii patches with versions accepted upstream
Replace patches for MediaTek Ethernet driver SGMII/SerDes unit with
their corresponding upstream patches. Not all of the patches in our
tree went upstream as-is, some are slightly different implementations,
and they require the phylink_pcs helpers now made available.

+Subject: [PATCH 01/10] net: mtk_eth_soc: add definitions for PCS
+
+As a result of help from Frank Wunderlich to investigate and test, we
+know a bit more about the PCS on the Mediatek platforms. Update the
+definitions from this investigation.
+
+This PCS appears similar, but not identical to the Lynx PCS.
+
+Although not included in this patch, but for future reference, the PHY
+ID registers at offset 4 read as 0x4d544950 'MTIP'.

+Subject: [PATCH 02/10] net: mtk_eth_soc: eliminate unnecessary error handling
+
+The functions called by the pcs_config() method always return zero, so
+there is no point trying to handle an error from these functions. Make
+these functions void, eliminate the "err" variable and simply return
+zero from the pcs_config() function itself.

+Add support for forcing the link speed and duplex setting in the
+pcs_link_up() method for out of band modes, which will be useful when

+to force duplex for 802.3z modes to work correctly.

+
+The PHY power up is common to both configuration paths, so move it into
+the parent function. We need to do this for all serdes modes.

+
+As a result of help from Frank Wunderlich to investigate and test, we
+now know how to program this PCS for in-band 802.3z negotiation. Add
+support for this by moving the contents of the two functions into the
+common mtk_pcs_config() function and adding the register settings for
+802.3z negotiation.
