On a kernel config with ALTIVEC=y and PPC_FPU not set/enabled,
there is a build error:
drivers/cpufreq/pmac32-cpufreq.c:262:2: error: implicit declaration of function
'enable_kernel_fp' [-Werror,-Wimplicit-function-declaration]
enable_kernel_fp();
so add a stub function for that when PPC_FPU is not set.
