[AVR] Fix def state of operands

Some instructions (especially mov+pop instructions) were setting the
wrong operands. For example, the pop instruction had the register set as
a source operand while it is a destination operand (the value is loaded
into the register).

I have found these issues using the machine verifier and using manual
code inspection.
