This series adds ns16550 support for two PCIe serial adapters found on
market:

 - WCH (Nanjing Qinheng Microelectronics) CH382, available as
   CH382 2S [1c00:3253] and CH382 2S1P [1c00:3250].
 - ASIX AX99100 PCIe to Multi-I/O Controller [125b:9910].

Both chips expose 16550-compatible UARTs through PCI I/O BAR0 and
work with the existing ns16550 driver once a matching device table
entry and parameter set are added.

v5:
 - Add Acked-by from Roger.
 - New patch 1/3: Initialize booleans in uart_param[] with "true"
   instead of 1, as suggested by Roger.

v4:
 - Add Reviewed-by from Stefano.

v3:
 - New patch 2/2: add support for ASIX AX99100.
 - Add forgotten Reviewed-by from Denis in patch 1/2 (WCH CH382).

v2:
 - Reorder entries in ns16550_config to keep them sorted by device ID.
 - Rename PCI_VENDOR_ID_WCH to PCI_VENDOR_ID_WCHIC as WCH has multiple
   vendor IDs.
