Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20151217-1' into staging

target-arm queue:
 * i.MX CCM patches
 * support guest debug for AArch64 KVM
 * support power button on virt board via GPIO
 * clean up AArch32 singlestep code
 * raise exception on misaligned LDREX operands
 * soc-dma: use hwaddr instead of target_ulong in printf
 * explicitly mark some ARM device loads as little-endian
 * i.MX: add support for lower and upper interrupt in GPIO
