2bf4658b8c board: sl28: fix RGMII clock and voltage
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.

4ceb5c6db2 board: kontron: add sl28 support
Add basic support for the Kontron SMARC-sAL28 board. This includes just
the bare minimum to be able to bring up the board and boot linux.

For now, the Single and Dual PHY variant is supported. Other variants
will fall back to the basic variant.

In particular, there is no watchdog support for now. This means that you
have to disable the default watchdog, otherwise you'll end up in the
recovery bootloader. See the board README for details.
