-----------
core: Fix empty-page mapping for root cell on 32-bit systems

If the hypervisor memory is located right below 4G, we wrap around the
calculation of hyp_phys_end to 0 and map nothing. Fix this by expanding
both hyp_phys_end and - while at it - also hyp_phys_start to u64.

Fixes 4a3317bb02.
