ipq806x: clean up UART driver tx_byte function

The driver as it was copied from u-boot provided a function to
    transmit multiple characters in one invocation. This feature was not
    ported to coreboot, there is no need to maintain the complexity when
    only one character at a time is transmitted. It is also very desirable
    to get rid of a 1024 byte array allocated on the stack.

The array was necessary to allow to convert multiple newline
    characters in the transmit data flow into two character sequences
    CRLF. Now just a single word is enough to keep one or two characters
    to transmit.

[EDIT km: newline translation is now part of printk]

BUG=chrome-os-partner:27784
    TEST=verified that coreboot with the new code prints generates console
         output.
