Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180209' into staging

target-arm queue:
 * Support M profile derived exceptions on exception entry and exit
 * Implement AArch64 v8.2 crypto insns (SHA-512, SHA-3, SM3, SM4)
 * Implement working i.MX6 SD controller
 * Various devices preparatory to i.MX7 support
 * Preparatory patches for SVE emulation
 * v8M: Fix bug in implementation of 'TT' insn
 * Give useful error if user tries to use userspace GICv3 with KVM
