target-arm: Don't report presence of EL2 if it doesn't exist
We already modify the processor feature bits to not report EL3
support to the guest if EL3 isn't enabled for the CPU we're emulating.
Add similar support for not reporting EL2 unless it is enabled.
This is necessary because real world guest code running at EL3
(trusted firmware or bootloaders) will query the ID registers to
determine whether it should start a guest Linux kernel in EL2 or EL3.
