video: sh_mobile_lcdcfb: depends on HAVE_CLK.
This deifdefs the driver and adds an explicit HAVE_CLK dependency. Given that all SH platforms provide it, there is no reason to keep this as an ifdef. Other architectures that implement support for this driver will already have to provide clock framework support for timers and so on already, so adding this as an additional dependency is not terribly probematic.
