ramips: mt7621: disable highmem support and remove highmem offset patch

On MT7621 it was observed, that enabling highmem support causes a significant
performance drop, as documented in: https://github.com/openwrt/openwrt/issues/13151
By adjusting the highmem start offset, we avoid leaving any RAM unaddressable,
even on devices with 512 MB

Fixes: https://github.com/openwrt/openwrt/issues/13151
