mb/google/nissa/var/riven: add fw_config probe for storage devices

Browse Source 
1. Add STORAGE_UNKNOWN fw_config to enable all storage devices,
this is used for the first boot in factory.

2. Add fw_config probe to enable/disable devices in devicetree
instead of variant.c, it can avoid suspend(s0ix) fail issue.

BUG=b:328580882
TEST=On riven eMMC and UFS SKUs, boot to OS and run
`suspend_stress_test -c 10` pass.
