[patch 1/1] 8250_pci: fix pch uart matching

[Arnaud Patard]

The rules used to make 8250_pci "ignore" the PCH uarts are lacking pci subids
entries, preventing it to match and thus is breaking serial port support for
theses systems.

This has been tested on a nanoETXexpress-TT, which has a specifici uart clock.
