[dpdk-dev] [PATCH] eventdev: add PCI probe named convenience function

[Timothy McDaniel]

Add new internal wrapper function for use by pci drivers as a
.probe function to attach to an event interface.  Same as
rte_event_pmd_pci_probe, except the caller can specify the name.

Updated rte_event_pmd_pci_probe so as to not duplicate
code.
