powerpc/powernv: Define real-mode versions of OPAL XICS accessors

Forráskód böngészése 
This defines real-mode versions of opal_int_get_xirr(), opal_int_eoi()
and opal_int_set_mfrr(), for use by KVM real-mode code.

It also exports opal_int_set_mfrr() so that the modular part of KVM
can use it to send IPIs.
