mediatek: mt7988: add DT entries for WED

Add memory regions and devices used for wireless offloading to the
device tree for MT7988.

This allows using WED on devices with MT7988 SoC and MT7995E, MT7996E or
MT7992E wireless controllers.

Devices with 4 GiB of RAM (or more) will still need ajustments to avoid
running out of swiotlb entries.
