serial: 8250: omap: Support wakeup pinctrl state on suspend
UART can be used as a wakeup source for am62 from suspend to ram states.
To enable wakeup from UART am62 requires a wakeup flag being set in the
pinctrl.
If the device is marked as wakeup enabled, select the 'wakeup' pinctrl
state on suspend and restore the default pinctrl state on resume.
