====================
ARM64: Add Internal PHY support for Meson GXL

The Amlogic Meson GXL SoCs have an internal RMII PHY that is muxed with the
external RGMII pins.

In order to support switching between the two PHYs links, extended registers
size for mdio-mux-mmioreg must be added.

The DT related patches submitted as RFC in [3] will be sent in a separate
patchset due to multiple patchsets and DTSI migrations.

Changes since v2 RFC patchset at : [3]
 - Change phy Kconfig/Makefile alphabetic order
 - GXL dtsi cleanup

Changes since original RFC patchset at : [2]
 - Remove meson8b experimental phy switching
 - Switch to mdio-mux-mmioreg with extennded size support
 - Add internal phy support for S905x and p231
 - Add external PHY support for p230
