nb/intel/haswell/pcie.c: Add missing pre-ASPM init

Add devicetree configuration parameters for mainboard-specific settings,
and provide reasonable defaults, which should usually be good enough.
This is based on Haswell SA Reference Code version 1.9.0 (Nov 2014).

Tested on Asrock B85M Pro4, registers now have the expected values.
