I actually said:

"Please put these new register definitions in address order. This list
is first sorted by MMD and then by address. So these should be before
the definition of MV_V2_TEMP_CTRL."

Which you have partially done.

Clearly MV_V2_PORT_INTR_STS is at a lower address than
MV_V2_MAGIC_PKT_WORD0, so the list is not sorted as it originally was.

Apart from that, the rest of the patch looks good, thanks!
