[PATCH v2 4/6] soc: mediatek: devapc: rename variable for new IC support

[Matthias Brugger]

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.
