For new ICs, there are multiple devapc HWs for different subsys.
We add a field 'vio-idx-num' in DT to indicate the number of
devices controlled by each devapc.
To be backward compatible with old ICs which have only one devapc
HW, this field is not required. The 'vio-idx-num' info will be set
in compatible data instead.
