This support both sdhc1 and sdhc2 with WP and CD for the marxbot and
devboard mx31moboard baseboards.
sdhc2 is present on both, but is not directly included in the
mx31moboard file because a third baseboard (not supported yet) without
sdhc2 is planned.
Changes since v1: removed pin initialization from init/exit function and
taken different comments into account
Changes since v2: pin initialiation now is done in another patch for all
current mx31moboard pins

MXC GPIO controller does not support generation of interrupts on both

polarity on each interrupt. This follows an example of

Currently we depend on hardcoded base addresses for the interrupt

It is no longer present in newer cores. Unfortunately Freescale decided
to put the bit which decides between automotive clock path and consumer
clock path in the automotive clock path direction. With current code we
cannot detect the core revision, so just remove automotive path completely.

xfs_file_last_byte() needs to acquire ilock
The powerpc kernel always requires an Open Firmware like device tree
to supply device information. On systems without OF, this comes from
a flattened device tree blob. This blob is usually generated by dtc,
a tool which compiles a text description of the device tree into the
flattened format used by the kernel. Sometimes, the bootwrapper makes
small changes to the pre-compiled device tree blob (e.g. filling in
the size of RAM). To do this it uses the libfdt library.
Because these are only used on powerpc, the code for both these tools
is included under arch/powerpc/boot (these were imported and are
periodically updated from the upstream dtc tree).
However, the microblaze architecture, currently being prepared for
merging to mainline also uses dtc to produce device tree blobs. A few
other archs have also mentioned some interest in using dtc.
Therefore, this patch moves dtc and libfdt from arch/powerpc into
scripts, where it can be used by any architecture.
The vast bulk of this patch is a literal move, the rest is adjusting
the various Makefiles to use dtc and libfdt correctly from their new
locations.
