[PATCH v3 2/3] dt-bindings: pinctrl: sx150xq: allow gpio line naming

[Heiko Schocher <hs@denx.de>]

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.

Signed-off-by: Heiko Schocher <hs@denx.de>

'gpio-line-names' does not match any of the regexes: '-cfg$', 'pinctrl-[0-9]+'

Ignored, as it is a make output, which helps to understand the
reason for adding this patch.

Changes in v3:
- worked in comments from Krzysztof
  gpio-line-names should match the actual number of
  gpios of the device.

Changes in v2:
patch dt-bindings: pinctrl: sx150xq: allow gpio line naming new in v2
