net: fsl_enetc: Introduce enetc_dev_id()

Browse Source 
Introduce mapping function enetc_dev_id(), which converts PCIe BDF of
the ENETC into linear incrementing index usable e.g. as interface index.
This replaces the current ad-hoc calculation used in the code with a
dedicated function. No functional change.
