Attaching and detaching ethernet ports from an application
is not the same thing as physically removing a PCI device,
so clarify the flags indicating support. All PCI devices
are assumed to be physically removable, so no flag is
necessary in the PCI layer.

* Not all PMDs support detaching feature.
To know whether a PMD can support detaching, search for the
- "RTE_PCI_DRV_DETACHABLE" flag in PMD implementation. If the flag is
+ "RTE_ETH_DEV_DETAHABLE" flag in rte_eth_dev::data::dev_flags. If the
flag is
defined in the PMD, detaching is supported.
