Implement AR933x polled IO uart bus code.
This implements the bus transmit/receive/sigchg/ipend methods with a polled interrupt handler (ipend) rather than enabling hardware interrupts.
The FIFO is faked at 16 bytes deep for now, just so the transmit IO side doesn't suck too bad (the callout frequency limits how quickly IO is flushed to the sender, rather than scheduling the callout more frequently whilst there's active TX. But I digress.)
Tested:
* Atheros AP121 (AR9330) reference board, booting to multi-user interactive mode.
