This patch makes Versatile Express use the common clock framework instead of the plat-versatile implementation. It defines clock provider for VE's OSCs (clock generators) and registers all required fixed and variable clock sources (for both motherboard and core tile). This is a simple conversion of the existing state and will be extended (and migrated to drivers/clk) in the near future. Signed-off-by: Pawel Moll <pawel.moll@arm.com>
