[PATCH v3] rtc: omap: Support ext_wakeup configuration

[Marcin Niestroj <m.niestroj@xxxxxxxxxxxxxxxx>]

Hi,

This is third approach for adding support of ext_wakeup configuration
in OMAP RTC.
Developed and tested on ChiliBoard (am335x) using v4.6-rc2.

Changes v2 -> v3:
 * Use gpiochip_request_own_desc() instead of gpiod_get_array() to make
   it possible to rmmod and insmod module (as suggested by Grygorii
   Strashko)
 * Go a little lower level, so the gpio number and active_low flag
   (present in device-tree bindings) are not hidden by gpiolib
   implementation

Changes v1 -> v2:
 * Use gpiochip implementation to utilize existing device-tree bindings
   (as suggested by Tony Lindgren)
