usertools: add --status-dev option to devbind

Browse Source 
Script displays status for all device types and output is much
longer than it used to be. This makes harder to read script output.

This patch adds new --status-dev argument to the script to select
a device group to display status.

Supported device groups:
net
crypto
event
mempool

Sample usage:
./usertools/dpdk-devbind.py --status-dev mempool
