objtool: Support addition to set CFA base
On arm64, the compiler can set the frame pointer either
with a move operation or with and add operation like:
add (SP + constant), BP
For a simple move operation, the CFA base is changed from SP to BP.
Handle also changing the CFA base when the frame pointer is set with
an addition instruction.
