powerpc/booke: Add support for new e500mc core
The new e500mc core from Freescale is based on the e500v2 but with the following changes: * Supports only the Enhanced Debug Architecture (DSRR0/1, etc) * Floating Point * No SPE * Supports lwsync * Doorbell Exceptions * Hypervisor * Cache line size is now 64-bytes (e500v1/v2 have a 32-byte cache line) Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
