powerpc, 8xx: remove support for 8xx

There was for long time no activity in the 8xx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 8xx,
so remove it (with a heavy heart, knowing that I remove
here the root of U-Boot).

- * Notes :
- * 1.	#define __SIMULATE_ERROR__ to inject a CRC error into every 2nd TX
- *		packet to force the USB re-transmit protocol.
- *
- * 2.	#define __DEBUG_UDC__ to switch on debug tracing to serial console
- *	be careful that tracing doesn't create Hiesen-bugs with respect to
- *	response timeouts to control requests.
- *
- * 3.	This driver should be able to support any higher level driver that
- *	that wants to do either of the two standard UDC implementations
- *	Control-Bulk-Interrupt or  Bulk-IN/Bulk-Out standards. Hence
- *	gserial and cdc_acm should work with this code.
- *
- * 4.	NAK events never actually get raised at all, the documentation
- *	is just wrong !
- *
- * 5.	For some reason, cbd_datlen is *always* +2 the value it should be.
- *	this means that having an RX cbd of 16 bytes is not possible, since
- *	the same size is reported for 14 bytes received as 16 bytes received
- *	until we can find out why this happens, RX cbds must be limited to 8
- *	bytes. TODO: check errata for this behaviour.
- *
- * 6.	Right now this code doesn't support properly powering up with the USB
- *	cable attached to the USB host my development board the Adder87x doesn't
- *	have a pull-up fitted to allow this, so it is necessary to power the
- *	board and *then* attached the USB cable to the host. However somebody
- *	with a different design in their board may be able to keep the cable
- *	constantly connected and simply enable/disable a pull-up  re
- *	figure 31.1 in MPC885RM.pdf instead of having to power up the board and
- *	then attach the cable !
