Add support for MediaTek Gigabit Ethernet PHYs found in MT7530 and
MT7531 switches.
The initialization procedure is from the vendor driver, but due to lack
of documentation, the function of some register values remains unknown.

Add support for MT7530 interrupt controller to handle internal PHYs.
In order to assign an IRQ number to each PHY, the registration of MDIO bus
is also done in this driver.
