I prefer using plain __raw_writel rather than creating a new wrapper.
The reason is a series I created that gets rid of these kind of wrappers
in AT91 which decide during compile time on which SoC we are running.
The above is not one of these, but I think doing it without accessors
fits better into the series I created.
