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

- Removed `bootblock-y += variant.c` from Makefile.inc based on CL:3841120.(The infrastructure for selecting an appropriate firmware image to use the right descriptor is now ready so runtime descriptor updates are no longer necessary.).
