scripts/common: Use separate function for nvme driver lookup

Browse Source 
Check if given pci address is bound to nvme driver via a separate
function - this makes the task of getting list of the nvme devices
that can be used in tests a bit easier since we don't have to relay
on, e.g., gen_nvme.sh where the extra step to get said devices is
to parse the actual config.
