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.

Regarding the commit subject:
"soc: mediatek: devapc: rename variable for new IC support"
maybe something like:
"soc: mediatek: devapc: rename register variable infra_base"

Other then that looks good to me.

OK. I will fix it in the next version.
