Currently we return NULL for unset parameters. As we can't set them
back to NULL once set this is not very consistent. Return an empty
string instead.

Some devices need to be moved to the PCM970 source file later, because
in fact these devices are not installed on the main unit PCM038.

This patch prooved to be useful while working with a colleague on a single
machine. It allows to switch the user without editing /env/config by
just issuing:
export user=me
. Note, in bash this construct (i.e. an if without body) bails out with:
Syntax error: "fi" unexpected
but in hush it seems to do the right thing.

The trap relocation function trap_reloc can be used across several PPC
platforms and is added to the ppc library. Accordingly, the definition
of trap_reloc is removed from mach-mpc5xxx/start.S

cpu_read*() and cpu_wrire*() are precisely equal to __raw_read*() and
__raw_write*().
Striving for correctness we can replace all those __raw_*() with cpu_*()
as that's exactly what the former ones do.

file_to_sdram is used to load an initrd. The resource size is
then used to pass the initrd size to Linux. This means that
the resource size must exactly match the initrd size. Currently
this is not the case since we request the sdram region in chunks
of 8 Kbytes. Fix this by adjusting the resource size when the file
is loaded.

On a systax error we have to bail out of the shell instead of
setting inp->p to NULL and crash barebox with a NULL pointer
deref. This only happened in scripts.

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.
