[PATCH V2] 8250_pci.c change for fix hanging problem.

[saumah <saumah@gmail.com>]

8250_pci.c change for fix hanging problem while suspend machine. 8250_pci.c support the same vendor id and device id definition as sunix multi-I/O card driver, when the sunix multi-io borad driver is installed,there are two drivers to support the same sunix multi-io card,it will cause operation error.
