powerpc: ppc4xx: remove zeus support

This has not been converted to Generic Board, so should be removed.
(See doc/README.generic-board for details.)

-Storage of the board specific values (ethaddr...)
--------------------------------------------------
-
-The board specific environment variables that should be unique
-for each individual board, can be stored in the I2C EEPROM. This
-will be done from offset 0x80 with the length of 0x80 bytes. The
-following command can be used to store the values here:
-
-=> setdef de:20:6a:ed:e2:72 de:20:6a:ed:e2:73 AB0001
-
-	  ethaddr           eth1addr          serial#
-
-Now those 3 values are stored into the I2C EEPROM. A CRC is added
-to make sure that the values get not corrupted.
-
-
-SW-Reset Pushbutton handling:
------------------------------
-
-The SW-reset push button is connected to a GPIO input too. This
-way U-Boot can "see" how long the SW-reset was pressed, and a
-specific action can be taken. Two different actions are supported:
-
-a) Release after more than 5 seconds and less then 10 seconds:
-   -> Run POST
-
-   Please note, that the POST test will take a while (approx. 1 min
-   on the 128MByte board). This is mainly due to the system memory
-   test.
-
-b) Release after more than 10 seconds:
-   -> Restore factory default settings
-
-   The factory default values are restored. The default environment
-   variables are restored (ipaddr, serverip...) and the board
-   specific values (ethaddr, eth1addr and serial#) are restored
-   to the environment from the I2C EEPROM. Also a bootline parameter
-   is added to the Linux bootline to signal the Linux kernel upon
-   the next startup, that the factory defaults should be restored.
-
-The command to check this sw-reset status and act accordingly is
-
-=> chkreset
-
-This command is added to the default "bootcmd", so that it is called
-automatically upon startup.
-
-Also, the 2 LED's are used to indicate the current status of this
-command (time passed since pushing the button). When the POST test
-will be run, the green LED will be switched off, and when the
-factory restore will be initiated, the reg LED will be switched off.
-
-
-Loggin of POST results:
------------------------
-
-The results of the POST tests are logged in a logbuffer located at the end
-of the onboard memory. It can be accessed with the U-Boot command "log":
-
-=> log show
-<4>POST memory PASSED
-<4>POST cache PASSED
-<4>POST cpu PASSED
-<4>POST uart PASSED
-<4>POST ethernet PASSED
-
-The DENX Linux kernel tree has support for this log buffer included. Exactly
-this buffer is used for logging of all kernel messages too. By enabling the
-compile time option "CONFIG_LOGBUFFER" this support is enabled. This way you
-can access the U-Boot log messages from Linux too.
