Subject: [PATCH 2/2] omap: rx51: Enable RX-51 ambient light sensor

The driver is at staging/iio/light/tsl2563.c for now since the IIO subsystem
seems to be the preferred subsystems for such drivers now.

Enable it on the RX-51 for now. The ugly #include will get fixed when IIO
moves from staging to its own subsystem.
