arm64/sysreg: Get rid of the TCR2_EL1x SysregFields

Browse source

TCR2_EL1x is a pretty bizarre construct, as it is shared between
TCR2_EL1 and TCR2_EL12. But the latter is obviously only an
accessor to the former.

In order to make things more consistent, upgrade TCR2_EL1x to
a full-blown sysreg definition for TCR2_EL1, and describe TCR2_EL12
as a mapping to TCR2_EL1.

This results in a couple of minor changes to the actual code.
