oak: Change Kukui to use new FRID based cros_config

Kukui family uses multiple build targets and cannot fit with the
existing cros_config implementation using FDT compatible string.
We should use the new firmware ID based probing method, same as x86.

TEST=emerge-kukui mosys; Run 'mosys platform model' on krane and kukui.
