Secure Boot: Copy PHyp secure header into standard reserved memory area
This change alters where Hostboot copies the Phyp secure header; instead
of placing it in front of PHYP (PHyp HRMOR-4k), it instead redirects it to the
standard reserved memory area. By doing this, we prevent it from
unintentionally ending up in mirrored memory.
