nb/intel/haswell: Tidy up code and comments
- Reformat some lines of code
- Put names to all used MCHBAR registers
- Move MCHBAR registers into a separate file, for future expansion
- Rewrite several comments
- Use C-style comments for consistency
- Rewrite some hex constants
- Use HOST_BRIDGE instead of PCI_DEV(0, 0, 0)
Tested, it does not change the binary of Asrock B85M Pro4.
