When probing platform drivers let's check if corresponding devices have
"wakeup-source" property defined (either in device tree, ACPI, or static
platform properties) and automatically enable such devices as wakeup
sources for the system. This will help us standardize on the name for this
property and reduce amount of boilerplate code in the drivers.
