[PATCH 2/2] common: bootm: reuse cdev_get_linux_rootarg()

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

CONFIG_MMCBLKDEV_ROOTARG=y so far had no effect on the root= option
generated by $global.bootm.root_dev. Have the bootm code reuse
cdev_get_linux_rootarg(), so it behaves the same as with boot from
file system.
