powerpc/83xx: Fix build failure with FPU=n
Building eg. 83xx/mpc832x_rdb_defconfig with FPU=n, fails with:
arch/powerpc/platforms/83xx/suspend.c: In function 'mpc83xx_suspend_enter':
arch/powerpc/platforms/83xx/suspend.c:209:17: error: implicit declaration of function 'enable_kernel_fp'
209 | enable_kernel_fp();
Fix it by providing an enable_kernel_fp() stub for FPU=n builds,
which allows using IS_ENABLED(CONFIG_PPC_FPU) around the call to
enable_kernel_fp().
