Added support for application management interface. There are two types of commands supported: 1. Firmware IOCTLs: These ioctls are meant for firmware consumption. Driver acts as a transport for these. 2. Driver only IOCTLs: These ioctls are meant for driver consumption. Driver will serve these ioctls without sending them down to firmware.
