clk: uniphier: rework for better clock tree structure
U-Boot does not support fancy clock tree structures like the Linux common clock framework. Implement a simple clock tree model at the driver level. With this, the clock data will be simplified. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
