ARM clk could only source from divcore or hsrun_divcore. Follow what we already used on i.MX7D and i.MX8M SoCs, use imx_clk_hw_cpu API. When ARM core is running normaly, whether divcore or hwrun_divcore will finally source from SPLL_PFD0. However SPLL_PFD0 is marked with CLK_SET_GATE, so we need to disable SPLL_PFD0, when configure the rate. So add CORE and HSRUN_CORE virtual clk to make it easy to configure the clk using imx_clk_hw_cpu API. Since CORE and HSRUN_CORE already marked with CLK_IS_CRITICAL, no need to set ARM as CLK_IS_CRITICAL. And when set the rate of ARM clk, prograting it the parent with CLK_SET_RATE_PARENT will finally set the SPLL_PFD0 clk.
