[IA64] Convert ia64 to use int-ll64.h

It is generally agreed that it would be beneficial for u64 to be an
unsigned long long on all architectures.  ia64 (in common with several
other 64-bit architectures) currently uses unsigned long.  Migrating
piecemeal is too painful; this giant patch fixes all compilation warnings
and errors that come as a result of switching to use int-ll64.h.

Note that userspace will still see __u64 defined as unsigned long.  This
is important as it affects C++ name mangling.

[Updated by Tony Luck to change efi.h:efi_freemem_callback_t to use
 u64 for start/end rather than unsigned long]
