Subject: OMAPFB: remove exported udpate window
X-Git-Tag: firefly_0821_release~3680^2~1437^2^2~13

OMAPFB: remove exported udpate window

omapfb contains an exported omapfb_update_window function, which, at
some point in history, was used by a closed source SGX driver. This was
a hack even then, and should not be needed anymore. So remove it.
