Merge remote-tracking branch 'remotes/ehabkost/tags/machine-next-pull-request' into staging

Machine queue, 2018-08-17

* Allow machine classes to specify if boot device suffixes should
  be ignored by get_boot_devices_list()
* Tiny coding style fixup

* remotes/ehabkost/tags/machine-next-pull-request:
  fw_cfg: ignore suffixes in the bootdevice list dependent on machine class
  sysbus: always allow explicit_ofw_unit_address() to override address generation
  machine: Fix coding style at machine_run_board_init()
