Debug UART typo & clarification

Top.s: HAL_UARTStartUp takes 0's based UART numbers, so the debug setup would go wrong (if HAL_UARTStartUp actually checked the value).
UART.s: Re-express the baud register default value so its origin is clear.
Retagged as BCM2835-0_75 as the (non-debug) version is binary identical.
