core/init: ensure that HRMOR is zero at boot
We have only ever supported running with HRMOR = 0. Having a non-zero
HRMOR causes all real mode accesses to have the value of HRMOR bitwise
ORed into the address that would have been accessed. This causes issues
when accessing MMIO registers such as the XSCOMs.
