Memory regions on MPC85xx boards are incorrectly defined leading to
corruption when running memory tests. This patch updates the memory
layout of MPC85xx boards so that critical memory regions can be
correctly reserved during the memory test.
Tested on the P2020RDB and DA923RC.

This makes it possible to modify the tree in the handlers.
This is necessary because the initrd addresses are only
known inside the handlers, but not to the generic bootm
code.

arch/ppc/Kconfig is reworked to make the configuration environment
architecture neutral. All MPC5200 configuration is moved to the
MPC5200 architecture specific configuration file. These modifications
are reflected in the PCM030 board support.
arch/ppc/Makefile compilation directives are updated in preparation
for the introduction of future cpus/machines.
lib/time.c is moved to the architecture specific directory and the
building instructions updated in the Make files. The file is
cleaned up of unused code.
The definition of L1_CACHE_... is updated and CACHELINE_SIZE is
defined in ppc/include/asm/cache.h for future use by the mpc85xx.
The file mach-mpc5xxx/pci_mpc5200.c and mach-mpc5xxx/start.S are
updated accordingly.
The declaration of search_exception_table is moved in
include/asm/common.h because it is used across architectures.
mach-mpc5xxx/traps.c is also updated to reflect this change.
The definition of exception in asm/ppc_asm.tmpl is updated for future
use by the mpc85xx. The file starts.S in mach-mpc5xxx is updated
accordingly.

This patch makes TEXT_BASE a consistent per-arch config switch.
Additionally, it converts all TEXT_BASE occurences from string to hex.
