aarch64: vp9mc: Simplify the extmla macro parameters

Fold the field lengths into the macro.

This makes the macro invocations much more readable, when the
lines are shorter.

This also makes it easier to use only half the registers within
the macro.

This is cherrypicked from libav commit
5e0c2158fbc774f87d3ce4b7b950ba4d42c4a7b8.
