kernel: append DTB to kernel imagesumo-test
Instead of using dtbTool to create a DT image , and include it into the boot image, we append DTB to the compressed kernel image. the LK bootloader knows how to retrieve DTB , when they are appeneded to compressed kernel image. Note: * it only works with compressed image. * dtbToo also typically adds msm-ids into the DTB, recent versions of LK exist that allow a single DTB to be used without the msm-ids, in which case it will work fine. when using older LK version, it is needed to patch the kernel and include the msm-ids.
