swupdate: define variables for flash paths and volume names

Software update recipes ('core-image-base-swu' and 'dey-image-qt-swu') are able
to set default or customized values for:
 * In the CC6, the proper path for:
    * linux partition (default to '/dev/mmcblk0p1')
    * rootfs partition (default to '/dev/mmcblk0p3' if no encrypted, always
      '/dev/mapper/cryptroot' otherwise)
 * In the CC6UL, the proper volume name for
    * linux partition (default to 'linux')
    * rootfs partition (default to 'rootfs')
