8250_pci: fix pch uart matching
to my tty git tree which can be found at

in the tty-next branch.
The patch will show up in the next release of the linux-next tree

Subject: 8250_pci: fix pch uart matching
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.
