[dpdk-dev] [PATCH] usertools: reduce devbind status output

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 reduces output to the script into a device group which can be
defined with new -t,--type parameter to script.
Supported types:
net
crypto
mempool
eventdev
If no device type provided status will print net devices by default.
Sample usage:
./usertools/dpdk-devbind.py -s -t mempool
