[PATCH v2 18/26] ns16550: match when to define bdf with uart code

[Troy Kisky <troykiskyboundary@gmail.com>]

When switching defined(CONFIG_PCI) to CONFIG_IS_ENABLED(PCI)
bdf is no longer accessible. So add preprocessor protection
to avoid access.

Changes in v2:
- changed condition of when to include field bdf
- added protection to another instance of bdf in uart.c
- Thanks to Simon for getting this corrected
