Use DMA for receiving data from the UART [broken]

Currently, this works for receiving exactly one byte.  It'll give me an
interrupt upon reading a second, but it doesn't DMA it.  And then it just stops
sending the interrupts -- which is slightly better than before.

I can also get it stuck in an infinite loop of calling uart0_isr() by not
clearing the interrupt status.
