Replace unsigned long with xen_ulong_t in public/platform.h.
Also replace unsigned int with uint32_t for clarity. It is safe because
unsigned int are 4 byte sized and 4 byte aligned an all the supported
architectures.

(you surely wanted to CC Keir for a change to the public API)
"git grep -l unsigned.long -- xen/include/public/" produces:
xen/include/public/arch-arm.h
xen/include/public/arch-x86/hvm/save.h
xen/include/public/arch-x86/xen-x86_32.h
xen/include/public/arch-x86/xen-x86_64.h
xen/include/public/arch-x86/xen.h
xen/include/public/arch-x86_64.h
xen/include/public/io/fbif.h
xen/include/public/io/tpmif.h
xen/include/public/kexec.h
xen/include/public/nmi.h
xen/include/public/physdev.h
xen/include/public/platform.h
xen/include/public/sched.h
xen/include/public/trace.h
xen/include/public/xen.h
Are any of the others things we should clear up while we are here?
arch-arm.h: is legit, used for the guest handle param on 32bit
arch-x86*: I think we can discount arch-x86* for these purposes.
fbif.h: has "unsigned long pd[256];"
tpmif.h: has "unsigned long addr; /* Machine address of packet. */"
kexec.h: has several unsigned longs
nmi.h: I think ARM won't want PV NMI, it can use h/w facilities
physdev.h: apic stuff -- therefore x86 specific
sched.h: just a comment, which I think is out of date
trace.h: a comment, not sure if it implies something is wrong though
xen.h: mostly x86 specific PV interfaces, but multicall_entry
is a bit concerning but it seems we haven't implemented
multicalls on ARM yet!
Phew, I think we are mostly ok...
