Use DMAC for display everywhere
...
This mimics the way the Kendryte SDK does things—it is better because
the MMIO based SPI tends to sometimes lose synchonization when the CPU
doesn't keep up providing data fast enough.

DMAC!
...
Add basic DMAC support (SPI/LCD first).
The current implementation (adding _dma to LCD traits) is really, really
awkward and just for testing. Probably it would be better for the LCD to
own its own dedicated DMA channel to avoid having to pass them in
for every… single… thing…
