kukui: Use coreboot-sdk by default.
kukui has a very limited size for RO image. We found that
using coreboot-sdk brings us a lot of extra space on kukui, so
we decide to use coreboot-sdk
BRANCH=None
BUG=b:122874284
TEST=build both targes with emerge-kukui coreboot && make BOARD=kukui -B -j \
BOOTBLOCK=/build/kukui/firmware/kukui/coreboot/bootblock.bin
and compare the results of grep hey build/kukui/RO/ec.RO.map
1. with coreboot-sdk
0x000000000001d7c8 __hey_flash_used = ((LOADADDR (.data) + SIZEOF ...
0x000000000001d7c8 __image_size = __hey_flash_used
2. without coreboot-sdk
0x000000000001df48 __hey_flash_used = ((LOADADDR (.data) + SIZEOF ...
0x000000000001df48 __image_size = __hey_flash_used
and it saves 1940 byte in this case.
