Marc Zyngier 93fbc983b2 target/arm: Honor HCR_EL2.TID1 trapping requirements 
HCR_EL2.TID1 mandates that access from EL1 to REVIDR_EL1, AIDR_EL1
(and their 32bit equivalents) as well as TCMTR, TLBTR are trapped
to EL2. QEMU ignores it, making it harder for a hypervisor to
virtualize the HW (though to be fair, no known hypervisor actually
cares).

Do the right thing by trapping to EL2 if HCR_EL2.TID1 is set.
