[POWERPC] Fix arch/powerpc/platforms/powermac/pic.c when !CONFIG_ADB_PMU
When building arch/powerpc/platforms/powermac/pic.c when !CONFIG_ADB_PMU
we get the following warnings:
arch/powerpc/platforms/powermac/pic.c: In function 'pmacpic_find_viaint':
arch/powerpc/platforms/powermac/pic.c:623: warning: label 'not_found' defined but not used
This fixes it.
