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.)
