It's not entirely unreasonable for io-pgtable-arm to be built for
configurations with 32-bit phys_addr_t, where the compiler rightly
raises a warning about the 36-bit shift. That particular code path
should never actually *run* on those systems, but we still want it
to compile cleanly, which is easily done by using an unambiguous u64
as the intermediate type instead.

Oops, I managed to totally overlook that phys_addr_t would be
configuration-dependent, sorry :(

If this can't sneak in on top of the SMMU pull, I'll resend it 
as a fix for -rc1. It shouldn't be super-critical.

Applied it, thanks Robin.
