For new ICs, there are multiple devapc HWs for different subsys.
The number of devices controlled by each devapc (i.e. 'vio_idx_num')
will be set in DT for per devapc node.
On the other hand, for old ICs which have only one devapc HW, the
'vio_idx_num' info is set in compatible data.
To be backward compatible, the 'vio_idx_num' in compatible data is set
as the default value. Only when the default value is 0 will we get the
'vio_idx_num' from DT.

For new ICs, there are multiple devapc HWs for different subsys.
For example, there is devapc respectively for infra, peri, peri2, etc.
So we rename the variable 'infra_base' to 'base' for code readability.

There are 3 debug info registers in new ICs while in legacy ones,
we have only 2. We add a 'version' field in compatible data to
decide how we extract the debug info.
