Building with CONFIG_SPL_SMP=n results in:
arch/riscv/lib/spl.c: In function ‘jump_to_image_no_args’:
arch/riscv/lib/spl.c:33:6:
error: unused variable ‘ret’ [-Werror=unused-variable]
33 | int ret;
| ^~~
Define the variable ret as __maybe_unused.
Fixes: 191636e448 ("riscv: Introduce SPL_SMP Kconfig option for U-Boot SPL")
Fixes: 8c59f2023c ("riscv: add SPL support")
