clk: Add CLK_HW_INIT_FW_NAME macro using .fw_name in .parent_data
With the new clk parenting code, clk_init_data was expanded to include .parent_data, for clk drivers that have parents referenced using a combination of device tree clock-names, clock indices, and/or clk_hw pointers. Add a CLK_HW_INIT macro for specifying a single parent from the device tree using .fw_name in struct clk_parent_data. Signed-off-by: Chen-Yu Tsai <wens@csie.org>
