Krzysztof Karas ac1abb5be8 hotplug: add check for uio_pci_generic driver
Add a check for this driver and enable iova=pa mode when it is
detected.
Add an option for the hotplug application to force iova mode.

This is to avoid:

EAL:   Expecting 'PA' IOVA mode but current mode is 'VA', not initializing
EAL: Requested device 0000:86:00.0 cannot be used

while using hw_hotplug test.
