During hardware validation it was noticed that the clock isn't
continuously enabled when there is no link. This is because the 125MHz
clock is derived from the internal PLL which seems to go into some kind
of power-down mode every once in a while. The LS1028A expects a contiuous
clock. Thus enable the PLL all the time.
Also, the RGMII pad voltage is wrong, it was configured to 2.5V (that is
the VDDH regulator). The correct voltage is 1.8V, i.e. the VDDIO
regulator.
This fix is for the freescale/fsl-ls1028a-kontron-sl28-var1.dts.
