ARM: dts: socfpga: remove non-existent DAC from CycloneV devkit

There is no Rohm DAC on the CycloneV devkit according to the online
documentation for it that I could find, and it definitely does not have
a dh2228fv as this device does not actually exist! Remove the DAC node
from the devicetree as it is not acceptable to pretend to have a device
on a board in order to bind the spidev driver in Linux.
