powerpc: remove 4xx support

Browse Source 
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
* --------- --------------------- ---
* 09-Sep-98 Created MCG
* 02-Nov-98 Removed External arbiter selected message JWB
* 27-Nov-98 Zero out PTMBAR2 and disable in PTM2MS JWB
* 04-Jan-99 Zero out other unused PMM and PTM regs. Change bus scan MCG
* from (0 to n) to (1 to n).
* 17-May-99 Port to Walnut JWB
* 17-Jun-99 Updated for VGA support JWB
* 21-Jun-99 Updated to allow SRAM region to be a target from PCI bus JWB
* 19-Jul-99 Updated for 405GP pass 1 errata #26 (Low PCI subsequent MCG
* target latency timer values are not supported).
* Should be fixed in pass 2.
* 09-Sep-99 Removed use of PTM2 since the SRAM region no longer needs JWB
* to be a PCI target. Zero out PTMBAR2 and disable in PTM2MS.
* 10-Dec-99 Updated PCI_Write_CFG_Reg for pass2 errata #6 JWB
* 11-Jan-00 Ensure PMMxMAs disabled before setting PMMxLAs. This is not
* really required after a reset since PMMxMAs are already
* disabled but is a good practice nonetheless. JWB
* 12-Jun-01 stefan.roese@esd-electronics.com
* - PCI host/adapter handling reworked
* 09-Jul-01 stefan.roese@esd-electronics.com
* - PCI host now configures from device 0 (not 1) to max_dev,
* (host configures itself)
* - On CPCI-405 pci base address and size is generated from
* SDRAM and FLASH size (CFG regs not used anymore)
* - Some minor changes for CPCI-405-A (adapter version)
* 14-Sep-01 stefan.roese@esd-electronics.com
* - CONFIG_PCI_SCAN_SHOW added to print pci devices upon startup
* 28-Sep-01 stefan.roese@esd-electronics.com
* - Changed pci master configuration for linux compatibility
* (no need for bios_fixup() anymore)
* 26-Feb-02 stefan.roese@esd-electronics.com
* - Bug fixed in pci configuration (Andrew May)
* - Removed pci class code init for CPCI405 board
* 15-May-02 stefan.roese@esd-electronics.com
* - New vga device handling
* 29-May-02 stefan.roese@esd-electronics.com
* - PCI class code init added (if defined)

---------------------------------------------------------------------
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'
