serial: clear LSR.TEMT when populating the TSR
We never actually clear the TEMT (transmit sending register empty) flag when populating the TSR. We set the flag, but since it's never cleared, setting it is sort of pointless.. I found this with a unit test case. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
