leds: Add openfirmware platform device support
Add bindings to support LEDs defined as of_platform devices in addition to
the existing bindings for platform devices.
New options in Kconfig allow the platform binding code and/or the
of_platform code to be turned on. The of_platform code is of course only
available on archs that have OF support.
The existing probe and remove methods are refactored to use new functions
create_gpio_led(), to create and register one led, and delete_gpio_led(),
to unregister and free one led. The new probe and remove methods for the
of_platform driver can then share most of the common probe and remove code
with the platform driver.
The suspend and resume methods aren't shared, but they are very short. The
actual led driving code is the same for LEDs created by either binding.
The OF bindings are based on patch by Anton Vorontsov
<avorontsov@ru.mvista.com>. They have been extended to allow multiple LEDs
per device.
