As FEAT_MOPS is not supported in guests yet, hide it from the ID
registers for guests.

The MOPS instructions are UNDEFINED in guests as HCRX_EL2.MSCEn is not
set in HCRX_GUEST_FLAGS, and will take an exception to EL1 if executed.

For my benefit, could you please explain why no support for guests yet?
Why not set HCRX_EL2.MSCEn in this series?
