Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20191025' into staging

target-arm queue:
 * raspi boards: some cleanup
 * raspi: implement the bcm2835 system timer device
 * raspi: implement a dummy thermal sensor
 * misc devices: switch to ptimer transaction API
 * cache TB flag state to improve performance of cpu_get_tb_cpu_state
 * aspeed: Add an AST2600 eval board
