16k: Move logic from device/google/shusky/BoardConfig-shusky-common.mk to zuma/BoardConfig-16k-common.mk
The makefile logic in device/google/shusky/BoardConfig-shusky-common.mk
is identical to the logic required for akita. Hence, this logic is
moved to device/google/zuma/BoardConfig-16k-common.mk to avoid
duplicating the file for akita.
