powerpc/mpic: Don't open-code dcr_resource_start
Don't open-code the OpenFirmware "dcr-reg" property lookup trying to map DCR resources. This makes the code a bit easier to read. Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
