This adds an MDIO driver for PIC64-HPSC/HX. The hardware supports C22 and C45 but only C22 is implemented in this commit. This MDIO hardware is based on a Microsemi design supported in Linux by mdio-mscc-miim.c. However, The register interface is completely different with pic64hpsc, hence the need for a separate driver. The documentation recommends an input clock of 156.25MHz and a prescaler of 39, which yields an MDIO clock of 1.95MHz. The hardware supports an interrupt pin or a "TRIGGER" bit that can be polled to signal transaction completion. This commit uses polling. This was tested on Microchip HB1301 evalkit with a VSC8574 and a VSC8541.
