serial: 8250_exar: add support for Advantech 2 port card with Device ID 0x0018
commit e7cbce761fe3fcbcb49bcf30d4f8ca5e1a9ee2a0 upstream.
The Advantech 2-port serial card with PCI vendor=0x13fe and device=0x0018
has a 'XR17V35X' chip installed on the circuit board. Therefore, this
driver can be used instead of theu outdated out-of-tree driver from the
manufacturer.
