[PATCH 1/5] dt-bindings: serial: 8250_omap: Add wakeup pinctrl state

[Markus Schneider-Pargmann <msp@baylibre.com>]

Pins associated with the 8250 omap unit can be the source of a wakeup in
deep sleep states. To be able to wakeup, these pins have to be
configured in a special way. To support this configuration add the
default and wakeup pinctrl states.
