powerpc/powernv: Create LED platform device
This patch adds platform devices for leds. Also export LED related OPAL API's so that led driver can use these APIs. Signed-off-by: Vasant Hegde <hegdevasant@linux.vnet.ibm.com> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
