Soby Mathew 99e58f9e69 Enable SCR_EL3.SIF bit ...

This patch enables the SCR_EL3.SIF (Secure Instruction Fetch) bit in BL1 and
BL31 common architectural setup code. When in secure state, this disables
instruction fetches from Non-secure memory.

NOTE: THIS COULD BREAK PLATFORMS THAT HAVE SECURE WORLD CODE EXECUTING FROM
NON-SECURE MEMORY, BUT THIS IS CONSIDERED UNLIKELY AND IS A SERIOUS SECURITY
RISK.

Fixes ARM-Software/tf-issues#372
