drivers/phy/m88e1512: Add new driver for Marvell PHY 88E1512

This driver enables the usage of an external Marvell PHY 88E1512 which
should be connected to a SOC internal MAC controller. In a first step it
is only the framework of the driver. Functionality will follow with a
second patch. To be able to use the driver, it is necessary to activate
the scan bus operation in the corresponding SOC TSN GbE driver.

One can change parameters in device tree so that the used setup can be
adapted in device tree to match the configuration of the device on the
mainboard.
