of: Only compile OF_DYNAMIC on PowerPC pseries and iseries
Only two architectures use the OF node reference counting and reclaim bits. There is no need to compile it for the rest of the PowerPC platforms or for any of the other architectures. This patch makes iseries and pseries select CONFIG_OF_DYNAMIC, and makes it default to off for everything else. It is still safe to turn on CONFIG_OF_DYNAMIC on all architectures, it just isn't necessary. v2: Also select OF_DYNAMIC for PPC_CHROMA and MPC885ADS as reported by Michael Meuling Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.
