tty: move drivers/serial/ to drivers/tty/serial/

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.

This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.

- *  linux/drivers/serial/pxa.c
- *
- *  Based on drivers/serial/8250.c by Russell King.
- *
- *  Author:	Nicolas Pitre
- *  Created:	Feb 20, 2003
- *  Copyright:	(C) 2003 Monta Vista Software, Inc.

- * it under the terms of the GNU General Public License as published by

- * (at your option) any later version.
- *
- * Note 1: This driver is made separate from the already too overloaded
- * 8250.c because it needs some kirks of its own and that'll make it
- * easier to add DMA support.
- *
- * Note 2: I'm too sick of device allocation policies for serial ports.
- * If someone else wants to request an "official" allocation of major/minor
- * for this driver please be my guest.  And don't forget that new hardware
- * to come from Intel might have more than 3 or 4 of those UARTs.  Let's
- * hope for a better port registration and dynamic device allocation scheme
- * with the serial core maintainer satisfaction to appear soon.
