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.

Can the threshold be set to 0? What should the behaviour be?

Some may want it to be invalid while some may want it to act as a "disable
notifications" toggle. So it's upto the drivers and their usecases, not for
us to decide. Will add this.
