Subject: [PATCH v2 1/1] dt-bindings: misc: add support for both property names cmd-gpios and cmd-gpio

The definition "gpio_suffixes[] = { "gpios", "gpio" }" shows that both
property names "cmd-gpios" and "cmd-gpio" are supported. But currently
only "cmd-gpios" is allowed in this yaml, and the name used in
mmp2-olpc-xo-1-75.dts is cmd-gpio. As a result, the following errors is
reported.

slave: 'cmd-gpios' is a required property
slave: 'cmd-gpio' does not match any of the regexes: 'pinctrl-[0-9]+'
