parport: parport_serial: Add WCH CH382L PCIe single parallel port support

The WCH CH382L PCIe adapter has 1 parallel port but unlike the similar
WCH CH328 adapter there are no serial ports connected to it.  Enable
this adapter with the addition of the appropriate PCIe IDs and board
support config.

PCIe device ID 1c00:3050:

02:00.0 Serial controller: Device 1c00:3050 (rev 10) (prog-if 05 [16850])
	Subsystem: Device 1c00:3050
	Flags: fast devsel, IRQ 16
	I/O ports at 2000 [size=256]
	Memory at d0000000 (32-bit, prefetchable) [size=32K]
	I/O ports at 2100 [size=4]
	Expansion ROM at b0200000 [disabled] [size=32K]
	Capabilities: [60] Power Management version 3
	Capabilities: [68] MSI: Enable- Count=1/32 Maskable+ 64bit+
	Capabilities: [80] Express Legacy Endpoint, MSI 00
	Capabilities: [100] Advanced Error Reporting
	Kernel driver in use: parport_pc
	Kernel modules: parport_pc, parport_serial
