This patch consists 2 or even 3 ones:
- whitespace shuffling (indentation fixes, blank lines), I dunno if
it's needed at all
- some new registers / bits
- actual switch to readl() / writel()

Please, split.

This would be better as a static inline helper, and name is completely
misleading, it doesn't mask the register bits, it _updates_ them.
