u-boot-dey: ccmp1/cc6ul: ensure 'rootfsvol' value in every case

When Dual Boot is not enabled, 'rootfsvol' variable must point to the
single boot system rootfs partition 'rootfs'.

Explicitly set this value. Otherwise the script relays on the default
rootfsvol value, which may be a Dual Boot partition.
