parentpowerpc: Remove include of linux/of_platform.h from asm/of_platform.h (diff)

powerpc: Update in-kernel dtc and libfdt to version 1.2.0
Some time ago, a copies of the upstream dtc and libfdt sources were included in the kernel tree to avoid having these as external dependencies for building the kernel. Since then development on the upstream dtc and libfdt has continued. This updates the in-kernel versions to match the recently released upstream dtc version 1.2.0. This includes a number of bugfixes, many cleanups and a few new features. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
