linux-qoriq: add merge_delta_config task

fsl-kernel-localversion added a separate task in which defconfig
is needed. But qoriq boards don't have a unified defconfig, different
KERNEL_DEFCONFIG should be copied as ${WORKDIR}/defconfig.

add a merge_delta_config task to merge kernel delta configs.
for ls1043ardb and ls2080ardb, freescale.config should be appended first.
