Now that alarm support for ISL12057 chip is available, let's use a
feature of the driver dedicated to NETGEAR ReadyNAS 2120 specific
routing of RTC IRQ#1 pin; on the device, this pin is not connected
to the SoC but to a PMIC, which allows the device to be powered
up when RTC alarm rings.
For that to work, the chip needs to be explicitly marked as a
device wakeup source using the "can-wakeup-machine" boolean
property. This makes 'wakealarm' sysfs entry available to
configure the alarm.
