When looking up the corresponding driver by algorithm type, since the driver does not save the algorithm type, it cannot be directly obtained. Therefore, the algorithm type should be saved during algorithm registration. Signed-off-by: Weili Qian <qianweili@huawei.com>
uadk adds API to support obtaining the current bandwidth utilization of a device. When the device driver creates the "dev_usage" file, users can obtain the current bandwidth utilization of the specified algorithm on the device by passing in the device and algorithm name to be queried.

uadk supports obtaining the bandwidth utilization of specified devices and algorithms through user-space drivers. After hardware resources are initialized, the bandwidth utilization can be directly obtained through the hardware mmio space, replacing the method of reading sysfs files and reducing system calls.

Supports obtaining the device's bandwidth utilization. For usage details, refer to "uadk_tool dfx --help". Signed-off-by: Weili Qian <qianweili@huawei.com>
