serial: txx9: Drop usage of uart_match_port()

Browse Source 
Where the uart_match_port() function is used it's known that .iotype is
UPIO_PORT. So uart_match_port() is equivalent to comparing .iobase.
Remove the call to uart_match_port() which then only has a single caller
that is handled in the next commit.
