[Arthur Heymans (Code Review)]

Hello Paul Menzel, build bot (Jenkins),

nb/intel/i945: Fix PEG port on 945gc

Vendor BIOS leaves UPMC1 untouched (on 945gc the default is 0x0203).

Not running PCIEx16 init which is valid for 945gm seems to fix all
issues and instabilities related to the PEG port.

According to lspci the link width is at the desired x16.
It is unknown if devices requesting a lower width work automatically
or need more configuration.
