[meta-freescale] [meta-fsl-arm-extra][PATCH v2 4/4] cubox-i: Add support to use uboot extlinux

[Fabio Berton]

Class that allows extlinux.conf generation for U-Boot use was introduced
on OE-core commits:

  - 7c18abeb2a6ef8b7bb53aa92a9ee76bd465fada2
  - 33df3a65f3e8e136811da715d0cc247ce66ae0ea

To use this feature we need to set UBOOT_EXTLINUX variable to 1.
u-boot-fslc commit 157ec06ef780e3dac510f35b6fcf496c22fb24f9 introduced
support to PARTUUID and UBOOT_EXTLINUX_ROOT use this feature to set
root path used by kernel cmdline.
