    serial: make uart_console_write->putchar()'s character an unsigned char

    Currently, uart_console_write->putchar's second parameter (the
    character) is of type int. It makes little sense, provided uart_console_write()
    accepts the input string as "const char *s" and passes its content -- the
    characters -- to putchar(). So switch the character's type to unsigned
    char.

    We don't use char as that is signed on some platforms. That would cause
    troubles for drivers which (implicitly) cast the char to u16 when
    writing to the device. Sign extension would happen in that case and the
    value written would be completely different to the provided char. DZ is
    an example of such a driver -- on MIPS, it uses u16 for dz_out in
    dz_console_putchar().

    Note we do the char -> uchar conversion implicitly in
    uart_console_write(). Provided we do not change size of the data type,
    sign extension does not happen there, so the problem is void.

    This makes the types consistent and unified with the rest of the uart
    layer, which uses unsigned char in most places already. One exception is
    xmit_buf, but that is going to be converted later.
