From: Graeme Gregory <quic_ggregory@quicinc.com>

The FRU devices for dc-scm-v1 and firework on bus IF_NONE.

-drive file=$DC_SCM_FRU,format=raw,if=none,unit=0
-drive file=$FIREWORK_FRU,format=raw,if=none,unit=1

file must match FRU size of 128k

Changes in v2:
 * Changed 'qcom_dc_scm_fru_init' to a generic one so that it can be used
   by other machines too. (Patrick)

This single patch was dropped from the series so I'm sending it again as a
separate patch.
