drm/amdgpu: added a sysfs interface for thermal throttling related V4
User can check and set the enablement of throttling logging and
the interval between each logging.
V2: simplify the sysfs interface(no string parsing)
V3: add proper lock protection on updating throttling_logging_rs.interval
V4: documentation cosmetic per Luben's suggestion
