powerpc/mm: Properly invalidate when setting process table base
The host process table base is stored in the partition table by calling the function native_register_process_table(). Currently this just sets the entry in memory and is missing a subsequent cache invalidation instruction. Any update to the partition table should be followed by a cache invalidation instruction specifying invalidation of the caching of any partition table entries (RIC = 2, PRS = 0). We already have a function to update the partition table with the required cache invalidation instructions - mmu_partition_table_set_entry(). Update the native_register_process_table() function to call mmu_partition_table_set_entry(), this ensures all appropriate invalidation will be performed.
