'akatsuki' is the codename of the Xperia XZ3 specifically, whereas
you declare this in the common file.
If they all should/can use the same binary, let's rename the path and
if they have to be separate, let's declare that
You can probably grab the firmware images for all three (four actually
but I don't know if anyone has the XZ2P) devices, dump it from the
bluetooth/vendor/firmware partition (can't recall where specifically)
and diff the files

I think it's usually bluetooth_<ab>. Corresponding image name is
BTFM.bin (if you have binary images).

Looks good, thou the path should follow `$Vendor/$codename` pattern.
In general, if it's generic firmware, fw path here should be
Sony/tama/
otherwise LGTM.
