[PATCH ARM 3/6]: Architectural Extensions - Security Extensions

[Matthew Gretton-Dann]

All,

The attached patch adds explicit support for Security Extensions to v7-A
and v6K, under the 'sec' architecture extension.

The majority of support was already available in the tools, but this
patch makes it explicitly separate from the base-line v7-A architecture.
It also corrects an issue where we would accept 'SMC' in v6T2 when in
fact it is not present until v7-A.
