arch-power: Fix extended opcode based decoding

When multiple instructions share the same primary opcode,
they are distinguished by the decoder by looking at the
extended opcode. However, the length and position of the
extended opcode field can vary based on instruction form.

This ensures that the correct extended opcode fields are
used for decoding such instructions.
