Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20160218-1' into staging

target-arm queue:
 * implement or fix various EL3 trap behaviour for system registers
 * clean up the trap/undef handling of the SRS instruction
 * add some missing AArch64 performance monitor system registers
 * implement reset for the PL061 GPIO device
 * QOMify sd.c and the pxa2xx_mmci device
 * SD card emulation fixes for booting Tianocore UEFI on RPi2
 * QOMify various ARM timer devices
