HRMOR relative addressing for PHyp SP ATTN area dump

This change adds absolute addresses to HDAT for the SP ATTN area
that the PHyp team can now use for predictably locating PHyp
debug information. In addition, Hostboot now populates attributes
with its intended PHyp ATTN area start addresses for FSP to read.
