remoteproc: mediatek: Extract SCP common registers
This is the 1st preliminary steps for probing multi-core SCP.
The registers of config and l1tcm are common on single-core SCP
and multi-core SCP. Extract these registers out to reduce duplicated
fields in mtk_scp when multiple SCP instances are created.
