parport_pc: add support for ASIX AX99100

commit 16aae4c6 upstream.

The PCI function 2 on ASIX AX99100 PCIe to Multi I/O Controller can be
configured as a single-port parallel port controller. The subvendor id
is 0x2000 when configured as parallel port. It supports IEEE-1284 EPP /
ECP with its ECR on BAR1.
