This is the preparation for probing multi-core SCP. The remoteproc
initialization flow is similar on cores and is reuesd to avoid
redundant code.
The registers of config and l1tcm are shared for multi-core
SCP. Reuse the mapped addresses for all cores.

That's not a common structure, but rather a commodity for internal flow: the right
place for this one is in mtk_scp.c
