Minimal P2020RDB platform support and configuration file ...

This is limited board support for the Freescale P2020RDB in single CPU
mode. The DDR is configured for a memory bus running at 667Mhz.
The system boots from NOR flash and provides the console at 115200
bauds, no other drivers are included.

Finally, the PPC Kconfig and make file make the building of
the P2020RDB platform firmware possible.

Preparation stage to support multiple PPC architectures ...

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.

Only pass -P to cpp when generating ld scripts ...

When building sandbox with ccache, one would hit warnings such as:
    warning: 'struct mmsghdr' declared inside parameter list
on random files; a way to reproduce this issue is to build a simple
file doing just:
    #include <sys/socket.h>

    int main(void) {
        return 0;
    }

    gcc -Wall -P -c -o foo foo.c

But actually the -P flag is only useful when generating non-C files,
such as linker scripts in the case of barebox.  Removing the -P flag
from all the gcc invocations, except when generating .lds files makes
the warning go away.  It turns out that this is what
linux/scripts/Makefile.build also does nowadays.

	 There is no generic linker script for ppc and blackfin
