ARC: [plat-hsdk] use actual clk driver to manage cpu clk

With corresponding clk driver now merged upstream, switch to it. - core_clk now represent the PLL (vs. fixed clk before) - input_clk represent the clk signal src for PLL (basically xtal) Signed-off-by: Eugeniy Paltsev <[email protected]> Signed-off-by: Vineet Gupta <[email protected]>
