treewide: Staticize and constify acpi ops

Set the acpi_ops structure as static const where applicable. The
The structure is not accessible from outside of drivers and is not
going to be modified at runtime. The structure may be unused in a
couple of drivers depending on their configuration, mark those
sites with __maybe_unused .
