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.
