FallenSigh 95fe94063c fix: revert UART FIFO batching — caused FIFO overflow + syserr on board ...

uart_puts(13B) + uart_puthex(8B) = 21 bytes without polling → FIFO overflow.
Board UART IP asserts AXI error → CPU syserr exception.
Simulation UART model is lenient, so sim passed but board failed.

Back to per-byte polling (safe).
