For FEAT_EVT, the HCR_EL2.TTLBOS bit allows trapping on EL1
use of TLB maintenance instructions that operate on the
outer shareable domain:
TLBI VMALLE1OS, TLBI VAE1OS, TLBI ASIDE1OS,TLBI VAAE1OS,
TLBI VALE1OS, TLBI VAALE1OS, TLBI RVAE1OS, TLBI RVAAE1OS,
TLBI RVALE1OS, and TLBI RVAALE1OS.
(There are no AArch32 outer-shareable TLB maintenance ops.)
Implement the trapping.
