mb/google/dedede/var/magolor: Select touchscreen based on SSFC in FW_CONFIG
Select touchscreen(s) based on touchscreen source provisioned in SSFC of CBI (higher 32 bits of FW_CONFIG in coreboot).
The reason is to avoid to enable multiple touchscreen ICs with the same slave address.
BUG=b:186609348
TEST=build and boot to OS.
