Why specify a speed of 0 here? Also, is there really a dh2228fv
connected or is this just a hack to let the Linux spidev driver match?

Zero in this case is indicates using SPI-controller maximum speed.
This can be overriden by using SPI_IOC_RD_MAX_SPEED_HZ IOCTL
for spidev device.
About using dh2228fv, of course no. Currently this is only one dt entry
for spidev exist, so yes, this a trick.

Then you should convince the spidev maintainers that whatever really is
connected there should be added to the spidev compatible list. Just
using an arbitrary binding only because the kernel happens to do the
right thing at the moment is not an option.
