We usually have WKUP and MCU UARTs as serial0 and serial1, we don't
have that many, so we would never have serial1, only 0 and 2. Might
be time we drop this odd numbering convention, at least for AM62L
class parts..

current-speed is only for UARTs that can't detect their current speed,
our UART and driver can, so this line isn't needed.
