Subject: [PATCH v4 25/25] scsi: ufs: mediatek: Add MT8196 compatible,
 update copyright

THe MT8196's UFS controller has a new compatible. Add the necessary
struct definitions to support it.

Also update the copyrights and authors, without tabs following spaces to
avoid checkpatch errors, to list myself as having contributed to this
driver after the preceding rework patches.
