Fix sparse warnings:

arch/powerpc/platforms/powernv/opal-psr.c:20:1:
 warning: symbol 'psr_mutex' was not declared. Should it be static?
arch/powerpc/platforms/powernv/opal-psr.c:27:3:
 warning: symbol 'psr_attrs' was not declared. Should it be static?
arch/powerpc/platforms/powernv/opal-powercap.c:20:1:
 warning: symbol 'powercap_mutex' was not declared. Should it be static?
arch/powerpc/platforms/powernv/opal-sensor-groups.c:20:1:
