[Accel-config] [PATCH v3 03/14] accel-config: Add lib functions to list mdevs and retrieve mdev properties

From: Ramesh Thomas <ramesh.thomas(a)intel.com>

Create library functions for querrying mdev details
- Functions to retrieve first and next mdev in list
- Macro to iterate mdev list
- Functions to retrieve mdev uuid and type
