It's useful to know the total number of underflow events and currently
the debug stats are getting reset each time CRTC is being disabled. Let's
account the overall number of events that doesn't get a reset.

Document opp-supported-hw property, which is not strictly necessary to
have on Tegra20, but it's very convenient to have because all other SoC
core devices will use hardware versioning, and thus, it's good to maintain
the consistency.
