fix(cm): make ICC_SRE_EL2 fixup generic to all worlds

For ICC_SRE_EL2.SRE the Arm ARM specifies that "If software changes this
bit from 1 to 0, the results are UNPREDICTABLE". However, the
indiscriminate zeroing of the EL2 context does just that for Secure and
Realm worlds. Make this fixup generic to avoid the problem.
