net: ethernet: mtk_wed: make memory region optional
Make mtk_wed_wo_memory_region optionals. This is a preliminary patch to introduce Wireless Ethernet Dispatcher support for MT7988 SoC since MT7988 WED fw image will have a different layout. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
