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.

-The configuration for the AMCC 440EP eval board "Bamboo" was changed
-to only use 384 kbytes of FLASH for the U-Boot image. This way the
-redundant environment can be saved in the remaining 2 sectors of the
-same flash chip.
-
-Caution: With an upgrade from an earlier U-Boot version the current
-environment will be erased since the environment is now saved in
-different sectors. By using the following command the environment can
-be saved after upgrading the U-Boot image and *before* resetting the
-board:
-
-setenv recover_env 'prot off FFF80000 FFF9FFFF;era FFF80000 FFF9FFFF;' \
-	'cp.b FFF60000 FFF80000 20000'
