Previously we used an alias the pci node to determine which node to fixup or delete. Now we use the new fdt_node_offset_by_compat_reg to find the node to update. Additionally, we replace the code in each board with a single macro call that makes assumes uniform naming and reduces duplication in this area. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
