Subject: [PATCH v4 4/7] soc: mediatek: devapc: rename register variable infra_base

From: Nina Wu <Nina-CM.Wu@...iatek.com>

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.
