zynqmp: pm: Implement PLL set parameter EEMI API
This API will be used to set a parameter for the PLL. The parameter
value that is set will have effect once the PLL mode is set to integer
or fractional mode. Parameter values represent the values as defined
in the Zynq MPSoC register reference manual ug1087.
