powerpc/32: Add a prepare_transfer_to_handler macro for exception prologs
In order to increase flexibility, add a macro that will for now call transfer_to_handler. As transfer_to_handler doesn't do the actual transfer anymore, also name it prepare_transfer_to_handler. The following patches will progressively remove the use of transfer_to_handler label.
