powerpc: remove 4xx support

There was for long time no activity in the 4xx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 4xx,
so remove it.

- *  Change Activity-
- *
- *  Date	Description of Change					    BY
- *  ---------	---------------------					    ---
- *  05-May-99	Created							    MKW
- *  27-Jun-99	Clean up						    JWB
- *  16-Jul-99	Added MAL error recovery and better IP packet handling	    MKW
- *  29-Jul-99	Added Full duplex support				    MKW
- *  06-Aug-99	Changed names for Mal CR reg				    MKW
- *  23-Aug-99	Turned off SYE when running at 10Mbs			    MKW
- *  24-Aug-99	Marked descriptor empty after call_xlc			    MKW
- *  07-Sep-99	Set MAL RX buffer size reg to ENET_MAX_MTU_ALIGNED / 16	    MCG
- *		to avoid chaining maximum sized packets. Push starting
- *		RX descriptor address up to the next cache line boundary.
- *  16-Jan-00	Added support for booting with IP of 0x0		    MKW
- *  15-Mar-00	Updated enetInit() to enable broadcast addresses in the
- *		EMAC0_RXM register.					    JWB
- *  12-Mar-01	anne-sophie.harnois@nextream.fr
- *		 - Variables are compatible with those already defined in
- *		  include/net.h
- *		- Receive buffer descriptor ring is used to send buffers
- *		  to the user
- *		- Info print about send/received/handled packet number if
- *		  INFO_405_ENET is set
- *  17-Apr-01	stefan.roese@esd-electronics.com
- *		- MAL reset in "eth_halt" included
- *		- Enet speed and duplex output now in one line
- *  08-May-01	stefan.roese@esd-electronics.com
- *		- MAL error handling added (eth_init called again)
- *  13-Nov-01	stefan.roese@esd-electronics.com
- *		- Set IST bit in EMAC0_MR1 reg upon 100MBit or full duplex
- *  04-Jan-02	stefan.roese@esd-electronics.com
- *		- Wait for PHY auto negotiation to complete added
- *  06-Feb-02	stefan.roese@esd-electronics.com
- *		- Bug fixed in waiting for auto negotiation to complete
- *  26-Feb-02	stefan.roese@esd-electronics.com
- *		- rx and tx buffer descriptors now allocated (no fixed address
- *		  used anymore)
- *  17-Jun-02	stefan.roese@esd-electronics.com
- *		- MAL error debug printf 'M' removed (rx de interrupt may
- *		  occur upon many incoming packets with only 4 rx buffers).
- *-----------------------------------------------------------------------------*
- *  17-Nov-03	travis.sawyer@sandburst.com
- *		- ported from 405gp_enet.c to utilized upto 4 EMAC ports
- *		  in the 440GX.	 This port should work with the 440GP
- *		  (2 EMACs) also
- *  15-Aug-05	sr@denx.de
- *		- merged 405gp_enet.c and 440gx_enet.c to generic 4xx_enet.c
-		  now handling all 4xx cpu's.
