configs/freescale_t1040d4rdb_defconfig: new board

The T1 QoriQ from NXP has had a few varients of RDB dev boards.
This target is against the latest D4RDB version.  Any of the
other versions before D4RDB (plain RDB), may require backing off
the uboot version to SDK 1.6 and/or adjusting the kernel dtb used.

This board configuration provides an upstream kernel build which
has been verified to boot on target.

The target assumes the user still uses the NXP suggested prebuilts
in the SDK2.0 (last release for PowerPC). If a uboot rebuild is
required, the source for SDK2.0 can be found in the following repo.
