clk: sandbox: Add sandbox test code for Common Clock Framework [CCF] This patch provides code to implement the CCF clock tree in sandbox. It uses all the introduced primitives; some generic ones are reused, some sandbox specific were developed. In that way (after introducing the real CCF tree in sandbox) the recently added to clk-uclass.c: clk_get_by_id() and clk_get_parent_rate() are tested in their natural work environment. Usage (sandbox_defconfig and sandbox_flattree_defconfig): ./u-boot --fdt arch/sandbox/dts/test.dtb --command "ut dm clk_ccf" Signed-off-by: Lukasz Majewski <lukma@denx.de>
