Subject: sparc: fix up arch_cpu_finalize_init() build breakage.
In commit b698b5d11a16 ("sparc/cpu: Switch to arch_cpu_finalize_init()") the
check for ARCH_HAS_CPU_FINALIZE_INIT was backported incorrectly to the SPARC
config option, not SPARC32. This causes build problems for the sparc64 arch:
sparc64-linux-ld: init/main.o: in function `start_kernel':
main.c:(.init.text+0x77c): undefined reference to `arch_cpu_finalize_init'
Fix this up by putting the option in the correct place.
