The send function, adf_iov_putmsg(), is shared by both PF and VF. This commit provides two direction specific APIs, adf_send_pf2vf_msg() and adf_send_vf2pf_msg() which decouple the implementation, which can change and evolve over time, from the user. With this change, the adf_iov_putmsg() is now isolated inside the file adf_pf2vf_msg.c and has been marked as static.
