serial: 8250_pci: Resolve WCH vendor ID ambiguity

[ Upstream commit 16076ca3a1565491bcb28689e555d569a39391c7 ]

There are two sites of the same brand: wch.cn and wch-ic.com.
They are property of the same company, but it appears that they
managed to get two different PCI vendor IDs. Rename them accordingly
using standard pattern, i.e. PCI_VENDOR_ID_...

While at it, move to PCI_VDEVICE() in the ID tables.
