mailbox: mtk-gpueb: Add missing 'static' to mailbox ops struct

mtk_gpueb_mbox_ops should be declared static. However, due to its const
nature, this specifier was missed, as it compiled fine without it and
with no warning by the compiler.

arc-linux-gcc (GCC) 12.5.0 doesn't seem to like it however, so add the
static to fix that.
