Subject: [PATCH AUTOSEL 6.12 2/8] serial: 8250_pci: Share WCH IDs with parport_serial driver

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

[ Upstream commit 535a07698b8b3e6f305673102d297262cae2360a ]

parport_serial driver uses subset of WCH IDs that are present in 8250_pci.
Share them via pci_ids.h and switch parport_serial to use defined constants.
