The IA64_HP_SIM dependency on PM_RUNTIME should be done in the arch
Kconfig instead of in the PM core.  Move it accordingly.

NOTE: arch/ia64/Kconfig currently does a 'select PM', which since
commit 1eb208ae (PM: Make CONFIG_PM depend on (CONFIG_PM_SLEEP ||
CONFIG_PM_RUNTIME)) is effectively a noop unless PM_SLEEP or
PM_RUNTIME are set elsewhere.
