ARM: generate imx dcd.S files as *.dcd.S ...

The compiled in dcd images generate an intermediate assembly file. Instead
of generating them as *.S generate them as *.dcd.S to better identify them
as generated files. These are then added to .gitignore.

kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp ...

Based on the same Linux commit from Stephen Warren:

commit b40b25f
Author: Stephen Warren <swarren@nvidia.com>
Date:   Wed Mar 6 10:58:37 2013 -0700

    kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp

    Replace cmd_dtc with cmd_dtc_cpp, and delete the latter.

    Previously, a special file extension (.dtsp) was required to trigger
    the C pre-processor to run on device tree files. This was ugly. Now that
    previous changes have enhanced cmd_dtc_cpp to collect dependency
    information from both gcc -E and dtc, we can transparently run the pre-
    processor on all device tree files, irrespective of whether they
    use /include/ or #include syntax to include *.dtsi.

Makefile.lib: introduce lwl-y for lowlevel code ...

The lowlevel code is expected to be present only ONCE

This fix the module support with PBL and allow to reduce the size of barebox
by drop the lowlevell init in barebox as the compiler does not discard it

This will allow to link compiled object to the built-in-pbl.o across the source

Now we compile the source %.c in pbl-%.o and provide -D__PBL__
so we can known in the source when it's compile for barebox or the pbl.
