[IBAL] Remove TO_LONG_PTR from IOCTL structures. Re-applied 1386 patch with out SMI changes.

This patch removes all instances of TO_LONG_PTR from internal IOCTL structures.  The only place TO_LONG_PTR should be used is in public structures that contain pointers and are exchanged between user-mode and kernel-mode.  Actually, the code should ideally have proxy structures for such API structures into which API structure members
are copied member-wise, and whose size is fixed.  Unused pointers should be stripped from the IOCTL proxy structures.  But that's a change for some other time...

All fields in internal IOCTL structures that were formerly TO_LONG_PTR are not uint64_t, and all uses have appropriate casts.
