macintosh/via-pmu: Add missing mmio accessors

Browse Source 
Add missing in_8() accessors to init_pmu() and pmu_sr_intr().

This fixes several sparse warnings:
drivers/macintosh/via-pmu.c:536:29: warning: dereference of noderef expression
drivers/macintosh/via-pmu.c:537:33: warning: dereference of noderef expression
drivers/macintosh/via-pmu.c:1455:17: warning: dereference of noderef expression
drivers/macintosh/via-pmu.c:1456:69: warning: dereference of noderef expression
