nb/intel/pineview: Clean up code and comments

- Reformat some lines of code
- Put names to all MCHBAR registers in a separate file
- Rewrite several comments
- Use C-style comments for consistency
- Rewrite some hex constants
- Use HOST_BRIDGE instead of PCI_DEV(0, 0, 0)
- Align a bunch of things

Tested with BUILD_TIMELESS=1, foxconn/d41s remains unaffected.
