target/arm: Remove CP_ACCESS_TRAP handling

There are no longer any uses of CP_ACCESS_TRAP in access functions,
because we have converted them all to use either CP_ACCESS_TRAP_EL1
or CP_ACCESS_TRAP_UNCATEGORIZED, as appropriate. Remove the handling
of bare CP_ACCESS_TRAP from the access_check_cp_reg() helper, so that
it now asserts if an access function returns a value requesting a
trap without a target EL.

Rename CP_ACCESS_TRAP to CP_ACCESS_TRAP_BIT, to make it clearer
that this is an internal-only definition, not something that
it makes sense to return from an access function. This should
help to avoid future bugs where we return the wrong syndrome
value by mistake.
