sparc64: Fix bootup regression due to perf init ordering.

Commit 004417a6d468e24399e383645c068b498eed84ad
("perf, arch: Cleanup perf-pmu init vs lockup-detector")
move the perf events init to be an early_initcall.

But this won't work properly unless the dependencies for
this code initialize beforehand.

Fix it by making cpu_type_probe and pcr_arch_init be
an early_initcall as well.
