[PATCH] dt-bindings: gpio: fsl,qoriq-gpio: allow gpio-hog child nodes

The binding sets additionalProperties: false and describes no child
nodes, so every gpio-hog on a QorIQ/Layerscape GPIO controller is a
dtbs_check failure:

  gpio@2310000 (fsl,ls2080a-gpio): 'ethsw-reset-hog', 'flash-reset-hog',
  'pltrst-hog', 'thermtrip-hog' do not match any of the regexes:
  '^pinctrl-[0-9]+$'

hogs are handled generically by gpiolib rather than by the controller
driver, so they work on this controller exactly as anywhere else, only
the schema disallows them.

Note: some other GPIO bindings already have such pattern:
gpio-mvebu, gpio-davinci, aspeed,ast2400-gpio and fairchild,74hc595
