[PATCH v1 2/4] ARM: dts: rockchip: remove unlikly-to-exist DAC from elgin-r1

[Conor Dooley]

From: Conor Dooley <conor.dooley at microchip.com>

The Rohm dh2228fv (really the bh2228fv, the compatible in the kernel has
a typo) does not support frequencies above 10 MHz, nor per the
datasheet appear to use either CPOL or CPHA. I suspect that this
devicetree is abusing the compatible in order to bind the spidev driver
in Linux. Pretending to have devices on a board for this purpose is not
acceptable, so remove it.

I could not find any documentation for this board online, and it does
not blatantly say that the device is a "spidev" like other [ab]users, so
it is possible there's actually a DAC here - but I doubt it is a
bh2228fv given the other incompatibilities.
