Justin Hibbits f77405e334 Use proper integer-pointer type conversions.
As part of an effort to extend Book-E to the 64-bit world, make the necessary
changes to the DPAA/dTSEC driver set to be integer-pointer conversion clean.
This means no more casts to int, and use uintptr_t where needed.

Since the NCSW source is effectively obsolete, direct changes to the source tree
are safe.
