OMAP: DSS2: DSI: remove auto-update perf measurement

Browse Source 
Remove performance measurement for auto-update. Auto-update and thus
performance measurement cannot be supported after the driver change where
the control is moved to display drivers.

This is part of a larger patch-set, which moves the control from omapdss
driver to the display driver.
