dt-bindings: pinctrl: sx150xq: allow gpio line naming

Adding gpio-line-names property works fine for this
device node, but dtb check drops warning:

'gpio-line-names' does not match any of the regexes: '-cfg$', 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/pinctrl/semtech,sx1501q.yaml#

Allow to add property gpio-line-names for this devices.
