ceaa97465f58cf2b3b4fc07a3b1067eb6f48d2e3 target/arm/helper: Fix tlbmask and tlbbits for TLBI VAE2*
When HCR_EL2.E2H is enabled, TLB entries are formed using the EL2&0
translation regime, instead of the EL2 translation regime. The TLB VAE2*
instructions invalidate the regime that corresponds to the current value
of HCR_EL2.E2H.
At the moment we only invalidate the EL2 translation regime. This causes
problems with RMM, which issues TLBI VAE2IS instructions with
HCR_EL2.E2H enabled. Update vae2_tlbmask() to take HCR_EL2.E2H into
account.
Add vae2_tlbbits() as well, since the top-byte-ignore configuration is
different between the EL2&0 and EL2 regime.
