mb/google/nissa/var/craaskov: Disable storage devices based on fw_config
Disable devices in variant.c instead of adding probe statements to
devicetree because storage devices need to be enabled when fw_config is
unprovisioned, and devicetree does not currently support this (it
disables all probed devices when fw_config is unprovisioned).
