mb/google/kukui: send SKU ID to EC for device-specific configuration 

For devices sharing same firmware, there may be few customization based
on SKU ID - for example being clamshell or form factor. On Kukui and
Jacuzzi platforms the SKU ID is defined on AP SOC, so we have to send
the information to EC.

BUG=b:161767717
TEST=make -j # builds and boots on Juniper
BRANCH=kukui
