Marc Zyngier d1e981c44b target/arm: Honor HCR_EL2.TID2 trapping requirements 
HCR_EL2.TID2 mandates that access from EL1 to CTR_EL0, CCSIDR_EL1,
CCSIDR2_EL1, CLIDR_EL1, CSSELR_EL1 are trapped to EL2, and QEMU
completely ignores it, making it impossible for hypervisors to
virtualize the cache hierarchy.

Do the right thing by trapping to EL2 if HCR_EL2.TID2 is set.

Backports commit 630fcd4d2ba37050329e0adafdc552d656ebe2f3 from qemu
