GCC 12 create a bogus array out of bounds warning as it assumes that
because there is special handling for `uart == 0` and `uart == 1`,
`uart` can indeed be `1`. There is an `assert(uart < UART_NUMOF)` above
that would blow up prior to any out of bounds access.
In any case, optimizing out the special handling of `uart == 1` for
when `UART_NUMOF == 1` likely improves the generated code and fixes
the warning.
