mb/protectli/vault_ehl: Set DIMM_MAX to 1

VP2420 (vault_ehl) has only 1 DIMM slot present. Set the DIMM_MAX to 1
to optimize the common libraries to not attempt to read and parse more
SPD than needed.

TEST=Boot Protectli VP2420 (vault_ehl) with different DIMMs and see
FSP is retraining the memory properly and fastboot is working.
