fix(cm): do not check for AArch32 support to enable features
EL3 is running in AArch64 mode so it is always able to enable all features. Some features are not implemented for AArch32 but that will be handled architecturally on changing exception levels so we don't need to worry about it. Always enable all features (checked on the FEAT_STATE flag of course) and save ourselves the check.
To prevent confusion in future, the SCR bits that actually affect AArch32 execution and must always be checked are moved up in the file and grouped together, rather than being straddled by feature enablement.
