powerpc/prom: Remove warning on array size when empty
When neither CONFIG_ALTIVEC, nor CONFIG_VSX or CONFIG_PPC64 is
defined, the array feature_properties is defined as an empty array,
which in turn triggers the following warning (treated as error on
W=1):

arch/powerpc/kernel/prom.c:298:16: error: comparison of unsigned expression < 0 is always false
for (i = 0; i < ARRAY_SIZE(feature_properties); ++i, ++fp) {
