The initial devicetree for PolarFire SoC incorrectly created a fixed
frequency clock in the devicetree to represent the msspll, but the
msspll is not a fixed frequency clock. The actual reference clock on a
board is either 125 or 100 MHz, 125 MHz in the case of the icicle kit.
Swap the incorrect representation of the msspll out for the actual
reference clock.
