  From: Frank Wunderlich <frank-w@public-files.de>

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.

v3:
- squashed version from sam
- v2 was ack'd by Krzysztof, but sams patch included updated emmc-names
  and different structure for uart to allow 2 pingroups
v2:
- wrap on col 80
