powerpc/85xx: Add support for setting up RAID engine liodns on P5020
Add support for Job Queue/Ring LIODN for the RAID Engine on P5020. Each Job Queue/Ring combo needs one id assigned for a total of 4 (2 JQs/2 Rings per JQ). This just handles RAID Engine in non-DPAA mode. Signed-off-by: Santosh Shukla <santosh.shukla@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
