mb/google/nissa/var/craask: 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).

BUG=b:263920313
TEST=Boot to OS on craask eMMC and NVMe SKUs with both unprovisioned
fw_config and fw_config set correctly.
