From 225c9a8d1da274bf23efec43ec28b1c9e45e12f8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] video: sh_mobile_lcdcfb: Support HAVE_CLK=n configurations.

This provides a workaround for users of sh_mobile_lcdcfb that don't
define HAVE_CLK and have otherwise sane clock initialization.

At the same time, move the sh_mobile_lcdc.h header to include/video/.
