tty: move obsolete and broken tty drivers to drivers/staging/tty/

As planned by Arnd Bergmann, this moves the following drivers to the
drivers/staging/tty/ directory where they will be removed after 2.6.41
if no one steps up to claim them.
	epca
	epca
	ip2
	istallion
	riscom8
	serial167
	specialix
	stallion

- *	Define a configuration structure to hold the board configuration.
- *	Need to set this up in the code (for now) with the boards that are
- *	to be configured into the system. This is what needs to be modified
- *	when adding/removing/modifying boards. Each line entry in the
- *	stli_brdconf[] array is a board. Each line contains io/irq/memory
- *	ranges for that board (as well as what type of board it is).
- *	Some examples:
- *		{ BRD_ECP, 0x2a0, 0, 0xcc000, 0, 0 },
- *	This line will configure an EasyConnection 8/64 at io address 2a0,
- *	and shared memory address of cc000. Multiple EasyConnection 8/64
- *	boards can share the same shared memory address space. No interrupt
- *	is required for this board type.
- *	Another example:
- *		{ BRD_ECPE, 0x5000, 0, 0x80000000, 0, 0 },
- *	This line will configure an EasyConnection 8/64 EISA in slot 5 and
- *	shared memory address of 0x80000000 (2 GByte). Multiple
- *	EasyConnection 8/64 EISA boards can share the same shared memory
- *	address space. No interrupt is required for this board type.
- *	Another example:
- *		{ BRD_ONBOARD, 0x240, 0, 0xd0000, 0, 0 },
- *	This line will configure an ONboard (ISA type) at io address 240,
- *	and shared memory address of d0000. Multiple ONboards can share
- *	the same shared memory address space. No interrupt required.
- *	Another example:
- *		{ BRD_BRUMBY4, 0x360, 0, 0xc8000, 0, 0 },
- *	This line will configure a Brumby board (any number of ports!) at
- *	io address 360 and shared memory address of c8000. All Brumby boards
- *	configured into a system must have their own separate io and memory
- *	addresses. No interrupt is required.
- *	Another example:
- *		{ BRD_STALLION, 0x330, 0, 0xd0000, 0, 0 },
- *	This line will configure an original Stallion board at io address 330
- *	and shared memory address d0000 (this would only be valid for a "V4.0"
- *	or Rev.O Stallion board). All Stallion boards configured into the
- *	system must have their own separate io and memory addresses. No
