[ 039/117] 8250_pci: fix pch uart matching

[Ben Hutchings]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnaud Patard <apatard@xxxxxxxxxxxxx>

commit aaa10eb1d0034eccc096f583fe308f0921617598 upstream.

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.
