BUS_PROT_WR(BIT(6), 0x2a0, 0x2a4, 0x228) repeates several times in the 
definition. Would it make sense to create a new define like we did with 
BUS_PROT_UPDATE_TOPAXI()? Are this offests are used in other SoCs.

In any case instead of magic numbers the values should be defined in 
include/linux/soc/mediatek/infracfg.h or appropiate header files.

Matthias
