Strashko, Grygorii 16669befb0 PM / wakeirq: fix wakeirq setting after wakup re-configuration from sysfs
Now wakeirq stops working for device if wakeup option for
this device will be reconfigured through sysfs, like:

echo disabled > /sys/devices/platform/extcon_usb1/power/wakeup
echo enabled > /sys/devices/platform/extcon_usb1/power/wakeup

Once above set of commands is executed the device's wakeup_source
opject will be recreated and dev->power.wakeup->wakeirq field will
contain NULL. As result, device_wakeup_arm_wake_irqs() will not arm
wakeirq for the affected device.

Hece, lets try to fix it in the following way:
  check for dev->wakeirq field when device_wakeup_attach() is called
  and if !NULL re-attach wakeirq to the device
