tty: move a number of tty drivers from drivers/char/ to drivers/tty/

As planned by Arnd Bergmann, this moves the following drivers from
drivers/char/ to drivers/tty/ as that's where they really belong:
	amiserial
	nozomi
	synclink
	rocket
	cyclades
	moxa
	mxser
	isicom
	bfin_jtag_comm

- *    Moxa Port Number Description:
- *
- *      MOXA serial driver supports up to 4 MOXA-C218/C320 boards. And,
- *      the port number using in MOXA driver functions will be 0 to 31 for
- *      first MOXA board, 32 to 63 for second, 64 to 95 for third and 96
- *      to 127 for fourth. For example, if you setup three MOXA boards,
- *      first board is C218, second board is C320-16 and third board is
- *      C320-32. The port number of first board (C218 - 8 ports) is from
- *      0 to 7. The port number of second board (C320 - 16 ports) is form
- *      32 to 47. The port number of third board (C320 - 32 ports) is from
- *      64 to 95. And those port numbers form 8 to 31, 48 to 63 and 96 to
- *      127 will be invalid.
