socfpga: Adding Clock Manager driver

Clock Manager driver will be called to reconfigure all the clocks setting based on user input. The input are passed to Preloader through handoff files Signed-off-by: Chin Liang See <clsee@altera.com> Cc: Albert Aribaud <albert.u.boot@aribaud.net> Cc: Tom Rini <trini@ti.com> Cc: Wolfgang Denk <wd@denx.de> CC: Pavel Machek <pavel@denx.de> Cc: Dinh Nguyen <dinguyen@altera.com> Acked-by: Pavel Machek <pavel@denx.de>
