powerpc/83xx: Add MCU LEDs support for MPC837xRDB and MPC8315RDB boards
There are two front-panel LEDs on MPC837xRDB and MPC8315RDB boards: PWR and HDD. After adding appropriate nodes we can program these LEDs from kernel and user space. Signed-off-by: Anton Vorontsov <avorontsov@mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
