AArch64 EL3: don't assume SCR_EL3's only nonzero bit is NS Make sure we initialize SCR_EL3 on startup and preserve bits in it across world switches. This is important for AArch64 because SCR_EL3 contains the register-width bit for EL1, and if the implementation is correctly honouring that bit then attempting to do an exception-return with it incorrectly set will result in an illegal exception return.
