Subject: add HAVE_CLK to Kconfig, for driver dependencies
From: David Brownell <dbrownell@xxxxxxxxxxxxxxxxxxxxx>
Flag platforms as HAVE_CLK (or not) in Kconfig, 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.)
