riscv: fix -Wundef warning for CONFIG_RISCV_BOOT_SPINWAIT
Since commit 80b6093b55e3 ("kbuild: add -Wundef to KBUILD_CPPFLAGS
for W=1 builds"), building with W=1 detects misuse of #if.
$ make W=1 ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- arch/riscv/kernel/
[snip]
AS arch/riscv/kernel/head.o
arch/riscv/kernel/head.S:329:5: warning: "CONFIG_RISCV_BOOT_SPINWAIT" is not defined, evaluates to 0 [-Wundef]
329 | #if CONFIG_RISCV_BOOT_SPINWAIT
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
CONFIG_RISCV_BOOT_SPINWAIT is a bool option. #ifdef should be used.
