Group the AVB pins into similar groups as found in other sh-pfc drivers.
The pins can not be muxed between functions other than AVB, but their
drive strengths can be controlled.
The group avb_mdc containing ADV_MDC and ADV_MDIO is called avb_mdio on
other SoCs. In pfc-r8a7796 the avb_mdc group already existed and is in
use in DT. Therefore add the ADV_MDIO pin to the existing group instead
of renaming it.
Based on commit b25719eb938eb39a ("pinctrl: sh-pfc: r8a7795: Add group
for AVB MDIO and MII pins").
