This patch adds the first parts of the 1588 support in the MSCC PHY, with registers definition and the 1588 block initialization. Those PHYs are distributed in hardware packages containing multiple times the PHY. The VSC8584 for example is composed of 4 PHYs. With hardware packages, parts of the logic is usually common and one of the PHY has to be used for some parts of the initialization. Following this logic, the 1588 blocks of those PHYs are shared between two PHYs and accessing the registers has to be done using the "base" PHY of the group. This is handled thanks to helpers in the PTP code (and locks). We also need the MDIO bus lock while performing a single read or write to the 1588 registers as the read/write are composed of multiple MDIO transactions (and we don't want other threads updating the page).
