Russell King a88d75b257 [SERIAL] Remove unconditional enable of TX irq for console 
A bug report from Gerd Hoffmann has highlighted that unconditionally
enabling the transmit interrupt at the end of console writes is very
bad.

In Gerd's case, it causes the test for buggy UARTs to give false
positives, incorrectly identifying ports as buggy when they are not.

Moreover, if we unconditionally enable the interrupt, and the port
is sharing it's interrupt with other ports, there is the very real
possibility that we'll cause an interrupt storm.  (Not all ports use
OUT2 as an interrupt mask.)

Hence, revert part of f91a3715db and
all of f5968b37b3 until a better solution
can be found.
