drm/ras: Introduce error threshold

Browse source 
Add get-error-threshold and set-error-threshold command support which
allows querying/setting error threshold of the counter. Threshold in RAS
context means the number of errors the hardware is expected to accumulate
before it raises them to software. This is to have a fine grained control
over error notifications that are raised by the hardware.
