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.

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.

We add a field 'vio-idx-num' in DT to indicate the number of

To be backward compatible with old ICs which have only one devapc

There are 3 debug info registers in new ICs while in legacy ones,
we have only 2. When dumping the debug info, we need to check first
if the 3rd debug register exists and then we can konw how to decipher
the debug info.

For new ICs, there are multiple devapc HWs for different subsys.
The number of devices controlled by each devapc (i.e. 'vio_idx_num'
in the code) varies.
We move this info from compatible data to DT so that we do not need
to add n compatible for a certain IC which has n devapc HWs

To support newer hardware architecture of devapc,
update device tree bindings.

The hardware architecture of mt8192 devapc is slightly
different from that of the previous IC.
We add necessary extensions to support mt8192 and be
back-compatible with other ICs.
