Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20170731' into staging
target-arm queue:
* fix broken properties on MPS2 SCC device
* fix MPU trace handling of write vs exec
* fix MPU M profile bugs:
- not handling system space or PPB region correctly
- not resetting state
- not migrating MPU_RNR

* remotes/pmaydell/tags/pull-target-arm-20170731:
hw/mps2_scc: fix incorrect properties
target/arm: Migrate MPU_RNR register state for M profile cores
target/arm: Move PMSAv7 reset into arm_cpu_reset() so M profile MPUs get reset
target/arm: Rename cp15.c6_rgnr to pmsav7.rnr
target/arm: Don't allow guest to make System space executable for M profile
target/arm: Don't do MPU lookups for addresses in M profile PPB region
target/arm: Correct MPU trace handling of write vs execute
