Marius Strobl 97202af2dc - Add a uart_rxready() and corresponding device-specific implementations ... that can be used to check whether receive data is ready, i.e. whether the subsequent call of uart_poll() should return a char, and unlike uart_poll() doesn't actually receive data. - Remove the device-specific implementations of uart_poll() and implement uart_poll() in terms of uart_getc() and the newly added uart_rxready() in order to minimize code duplication. - In sunkbd(4) take advantage of uart_rxready() and use it to implement the polled mode part of sunkbd_check() so we don't need to buffer a potentially read char in the softc. - Fix some mis-indentation in sunkbd_read_char().
