accel/amdxdna: Add error handling
When there is a hardware error, the NPU firmware notifies the host through
a mailbox message. The message includes details of the error, such as the
tile and column indexes where the error occurred.
The driver starts a thread to handle the NPU error message. The thread
stops the clients which are using the column where error occurred. Then
the driver resets that column.
