dmaengine: idxd: add configuration component of driver
The device is left unconfigured when the driver is loaded. Various components are configured via the driver sysfs attributes. Once configuration is done, the device can be enabled by writing the device name to the bind attribute of the device driver sysfs. Disabling can be done similarly. Also the individual work queues can also be enabled and disabled through the bind/unbind attributes. A constructed hierarchy is created through the struct device framework in order to provide appropriate configuration points and device state and status. This hierarchy is presented off the virtual DSA bus. i.e. /sys/bus/dsa/...
