Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180116' into staging

target-arm queue:
 * SDHCI: cleanups and minor bug fixes
 * target/arm: minor refactor preparatory to fp16 support
 * omap_ssd, ssi-sd, pl181, milkymist-memcard: reset the SD
   card on controller reset (fixes migration failures)
 * target/arm: Handle page table walk load failures correctly
 * hw/arm/virt: Add virt-2.12 machine type
 * get_phys_addr_pmsav7: Support AP=0b111 for v7M
 * hw/intc/armv7m: Support byte and halfword accesses to CFSR
