Subject: [PATCH 3.5 36/90] ARM: integrator_cp: Set LCD{0,1} enable lines when turning on CLCD

3.5.7.27 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jonathan Austin <jonathan.austin@....com>

commit 30aeadd44deea3f3b0df45b9a70ee0fd5f8d6dc2 upstream.

This turns on the internal integrator LCD display(s). It seems that the code
to do this got lost in refactoring of the CLCD driver.
