Compute PAYLOAD_BASE attr based on phys_addr passed from PHYP
PHYP is writing the physical address of their new HRMOR into the
provided hdat address. Hostboot will now take that physical address
and mask off 0 bit of the address. Also the PAYLOAD_BASE
attribute is the unit MB so we will divide the masked address by 1 MB
