arm: Fix SCFG ICID reg addresses

arm: Fix SCFG ICID reg addresses

On the LS102x boards, in order to initialize the ICID values of
masters, the dev_stream_id array holds absolute offsets from the
base of SCFG.

In ls102xa_config_ssmu_stream_id, the base pointer is cast to
uint32_t * before adding the offset, leading to an invalid address.
Casting it to void * solves the issue.
