[ Upstream commit c115e7f51e685536ecb885854bdd4b3f225ff3e4 ]
Fix mmc and uart pins after uart splitting.
Some pinmux pins of the mt7986 pinctrl driver is composed of multiple
pinctrl groups, the original binding only allows one pinctrl group
per dts node, this patch sets "maxItems" for these groups and add new
examples to the binding documentation.
