[RFC PATCH v1 0/2] Allow the RAS feature bit in ID_AA64PFR0_EL1 writable from userspace

Currently the RAS feature bit is not writable in ID_AA64PFR0EL1, this makes migration fail when migration from the machine which RAS is 1 to another machine which RAS is 2. Allow RAS writable from userspace would make the migration possible between two machines which RAS is different. Shaoqin
