imx: serial: fix one bit field type
"have_rtscts" is assigned 1, while it is declared int:1, two's complement, which can hold 0 and -1 only. The code works, as the upper bits are cut off, and tests are done against 0 only. Nonetheless, correctly declaring the bit field as unsigned int:1 renders the code more robust.
