[PATCH v3 17/23] ns16550: match when to define bdf with uart code

[Troy Kisky]

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

(no changes since v2)

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
