Revert "wifi: mt76: mt7996: fill txd by host driver"

Browse Source 
This reverts commit 3b522cadedfe6e9e0e8193d7d4ab5aa8d0c73209.

The MTK connac3 has introduced new hardware, SDO (Software Defined
Offload), to offload the process of filling the TX descriptor. Initially,
there were some issues, but after several fixes, it should now be stable,
allowing us to revert this commit.

Additionally, activating SDO is essential for the proper functioning of
features like TX checksum offload.
