ACPI / scan: Add static attribute to indirect_io_hosts[]
Array indirect_io_hosts[] is declared in acpi_is_indirect_io_slave() as a const array, which means that the array will be re-built for each call. Optimise by adding the static attribute, which means that the array is added to const-data pool and not re-built per function call.
