[PATCH] dt-bindings: pinctrl: mt7622: allow gpio-hogs

[Chen-Yu Yeh]

Commit 6e3b067d3c5e ("arm64: dts: mediatek: mt7622: Align GPIO hog
name with bindings") renamed the asm_sel GPIO hog to asm-sel-hog to
follow the GPIO hog naming convention, but the mt7622 pinctrl binding
only allows child nodes matching '-pins(-[a-z]+)?$', causing a
dtbs_check warning:

  mt7622-bananapi-bpi-r64.dtb: pinctrl at 10211000 (mediatek,mt7622-pinctrl):
  'asm-sel-hog' does not match any of the regexes:
  '-pins(-[a-z]+)?$', '^pinctrl-[0-9]+$'

Allow gpio-hog nodes in the pinctrl node, following the same pattern
as commit 9322da935c9a ("dt-bindings: pinctrl: mt7988: allow
gpio-hogs").
