x86: bootm: Add dm_remove_devices_flags() call to bootm_announce_and_cleanup()
This patch adds a call to dm_remove_devices_flags() to
bootm_announce_and_cleanup() so that drivers that have one of the removal
flags set (e.g. DM_FLAG_ACTIVE_DMA_REMOVE) in their driver struct, may
do some last-stage cleanup before the OS is started.
