Treewide: remove address of the Free Software Foundation ...

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

serial_ns16550: change the driver's name ...

The name "serial_ns16550" is not handy because the devices
will have the names like "serial_ns165500", "serial_ns165501",
"serial_ns165502" etc.

The names like "ns16550_serial0" and "ns16550_serial1" look
much better.

Also it is reasonable to make serial driver's names unification.
E.g. see the names for drivers in drivers/serial directory:
 "netx_serial",
 "mpc5xxx_serial",
 "altera_serial",
 "s3c_serial",
 "imx_serial",
 "pxa_serial",
 "blackfin_serial",
 "stm_serial",
 "pl010_serial",
and even "g_serial" in ./drivers/usb/gadget/serial.c

ns16550: fix ier selection ...

The document "PC16550D Universal Asynchronous
Receiver Transmitter with FIFOs" (vers. June 1995,
http://www.national.com/ds/PC/PC16550D.pdf) states
that IER (Interrupt Enable Register) is accessible
if the bit DLAB = 0 (DLAB is bit 7 in LCR; in barebox
DLAB known as LCR_BKSE).

So before IER access we need set DLAB to 0.
