mb/google/nissa/var/yaviks: Remove fw_config probe for storage devices

When fw_config is unprovisioned, devicetree will disable all probed
devices. However, boot-critical devices such as storage devices need to
be enabled.

As a temporary workaround while adding devicetree support for this,
remove the fw_config probe for storage devices so that all storage
devices are always enabled. On eMMC SKUs, UFS and ISH will be disabled
by the PCI scan anyway. On UFS SKUs, eMMC is not disabled by the PCI
scan, but keeping it enabled should have no functional impact, only a
possible power impact.

BUG=b:251055188
TEST=On yaviks eMMC and UFS SKUs, boot to OS and
`suspend_stress_test -c 10`
