add HAVE_CLK to Kconfig, for driver dependencies
Flag platforms as HAVE_CLK (or not) in Kconfig, based on whether they support <linux/clk.h> calls, so that otherwise portable drivers which need those calls can list that dependency. Something like this is a prerequisite for merging the musb_hdrc driver, currently used on platforms including Davinci, OMAP2430, OMAP3xx ... and the discrete TUSB6010 chip, which doesn't have a natural platform dependency. (Used with OMAP 2420 in current Nokia N8x0 tablets.)
