zynqmp: pm: Set PLL fractional data using PLL set parameter EEMI API
Fractional data should be set using PLL set parameter EEMI API. This stands for system-level communication (APU to PMU). Since linux already uses a specific IOCTL function to do this and we need to keep it that way, the pll clock ID given by linux has to be mapped to the pll node ID that is communicated at the system-level (argument of PLL set parameter API). With this modification the function pm_api_clk_set_pll_frac_data is removed from pm_api_clock.c/h because it became unused.
