nb/intel/sandybridge: Tidy up code and comments
- Reformat some lines of code
- Move MCHBAR registers and documentation into a separate file
- Add a few missing macros
- Rename some registers
- Rewrite several comments
- Use C-style comments for consistency
- Rewrite some hex constants
- Use HOST_BRIDGE instead of PCI_DEV(0, 0, 0)
With BUILD_TIMELESS=1, this commit does not change the result of:
- Asus P8Z77-V LX2 with native raminit.
- Asus P8Z77-M PRO with MRC raminit.
