disp: msm: sde: remove HARD_RESET recovery event on frame-timeouts only

On frame timeouts, the driver should only be responsible for
reporting the error event to user space clients. Handling of
the error events should be left to the user space clients.

This change removes explicit mechanism in SDE driver to track
error events for a pre-defined threshold levels and RESET hints
sent to the user space on handling those error events during
frame timeouts.
