feat(tc): enable SME and SME2 options for TC4

Browse source 
Set the Make flags for TF-A to be able to enable SME and SME2 features.
Note that we enable these architectural features for both the secure and
non-secure worlds, which is required on TC4.

In the case of the non-secure world, we specify a value of 2 for the
flag which specifies that TF-A should check the feature register to
ensure that the feature is present before enabling it. This allows these
flags to be compatible with all platforms and stops TF-A doing anything
different if it does not detect that the feature is present.
