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.
