These patches add support to KVM to enable MTE within a guest. They are
based on Catalin's v6 MTE user-space support series[1]. Changes since
the previous RFC posting[2]:
* Correctly read/write TFSR_EL1 using {read,write}_sysreg_el1()
* Set SCTLR_EL2.ITFSB bit for non-VHE
* Minor updates to deal with rebasing
