The refactoring is a really good idea and I like it.

Acked-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006 at gmx.net>

(The fixup patch for BAR5 is a separate issue and I have to reinvestiage
what I tried to debug/fix back then.)

I don't think we can abort on timeouts. satasii_chip_writeb() returns
void. We would have to change all chip_write[bwl]() and all
chip_read[bwl]() functions to allow for error handling. Not sure if that
is worth it.
