hwrng: omap3-rom - Fix unused function warnings
When runtime-pm is disabled, we get a few harmless warnings:
drivers/char/hw_random/omap3-rom-rng.c:65:12: error: unused function 'omap_rom_rng_runtime_suspend' [-Werror,-Wunused-function]
drivers/char/hw_random/omap3-rom-rng.c:81:12: error: unused function 'omap_rom_rng_runtime_resume' [-Werror,-Wunused-function]
Mark these functions as __maybe_unused so gcc can drop them
silently.
Fixes: 8d9d4bdc495f ("hwrng: omap3-rom - Use runtime PM instead of custom functions")
