Make it static, and move it inside the function to avoid a "defined but
not used" warning if CONFIG_DMA_CMA=n.

Commit 0ca2894b5a900709 ("ARM: shmobile: Use shared SCU SMP boot code on
r8a7779") obsoleted the r8a7779-specific SCU boot code, but forgot to
remove the setup of shmobile_boot_fn and shmobile_boot_arg, which is
overwritten by shmobile_smp_scu_prepare_cpus().
Note that shmobile_scu_base wasn't initialized at that point yet anyway.
