MIPS: DTS: CI20: multiple DTS improvements
a) add DT node for SW1 as Enter button
The SW1 button can be used as a simple one-button keyboard
and is connected to PD17.
Note: SW1 has a second meaning to change the boot sequence
when pressed while powering on.
b) give eth0_power a defined voltage.
This is a 3.3V power switch (DVNET3.3V).
