Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180629' into staging

target-arm queue:
 * last of the SVE patches; SVE is now enabled for aarch64 linux-user
 * sd: Don't trace SDRequest crc field (coverity bugfix)
 * target/arm: Mark PMINTENSET accesses as possibly doing IO
 * clean up v7VE feature bit handling
 * i.mx7d: minor cleanups
 * target/arm: support reading of CNT[VCT|FRQ]_EL0 from user-space
 * target/arm: Implement ARMv8.2-DotProd
 * virt: add addresses to dt node names (which stops dtc from
   complaining that they're not correctly named)
 * cleanups: replace error_setg(&error_fatal) by error_report() + exit()
