Update clk_init_data to const and also use index instead of fw_name for
graphics, lpasscc and video clock controller.

Fixes: 3e0f01d6c7e74 ("clk: qcom: Add graphics clock controller driver for SC7280")
Fixes: 4ab43d171181d ("clk: qcom: Add lpass clock controller driver for SC7280")
Fixes: fae7617bb1428 ("clk: qcom: Add video clock controller driver for SC7280")

What is the benefit from using indices here? In my opinion the code
becomes more fragile with such a change.
