Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180302' into staging

target-arm queue:
 * implement FCMA and RDM v8.1 and v8.3 instructions
 * enable Cortex-M33 v8M core, and provide new mps2-an505 board model
   that uses it
 * decodetree: Propagate return value from translate subroutines
 * xlnx-zynqmp: Implement the RTC device
