Clear out HOMER attributes and reset PM in PHYP mode
During the IPL, Hostboot will initialize part of the PM Complex and setup the HOMER memory spaces. At runtime, PHYP will reinit the complex with its own memory spaces. This change explicitly resets the complex and clears any related HOMER attributes before jumping to PHYP so that the first call at runtime starts completely fresh.
