sb/intel/lynxpoint: Do not determine PCH type at runtime
Both PCH types are very different, and mixing the code for both together
isn't useful. First of all, inline `pch_is_lp` to return a constant.
This allows the compiler to optimize out unused code, which results in
smaller executables. For the Asrock B85M Pro4, it's about 2.5 KiB less.
Subsequent commits will further split the southbridge code.
