From: lijiaming3 <lijiaming3@xxxxxxxxxx>
UFS descriptors assumed to have a 2 bytes header:
- Offset 0 - descriptor size
- Offset 1 - descriptor id
However, the ufs spec does not mandates this, and as a matter of
fact, QUERY_DESC_DESC_TYPE_OFFSET is not being used anymore now.
And future descriptors no longer follow this assumption. So
remove this as preparation of introducing the FBO descriptor.
