Rewrite the SB600 chipset enable function

- Check for read/write protected regions first.
- Region protection is write-once according to the data sheets. Check if
the write succeeded. Don't write if the region is not protected.
- Verbose region protection dumping.
- Improve readability of BAR mapping code.
- Align BAR mapping to a page boundary (4k) instead of a 16k boundary.

This patch prepares the code for a SPI detection heuristic.

Corresponding to flashrom svn r463.
