Subject: [PATCH] NFC: pn533: Add a new pn533_send_cmd_async iface

This is intendend to replace pn533_send_cmd_frame_async() which
requires from the caller to create a complete frame.

The new function constructs a frame and sends it out which hides the
frame logic and avoid code duplication.

The caller has to allocate skb and put its payload there, and finally
provide the skb together with a complete cb to pn533_send_cmd_async().

Response skb is allocated by the core part and pass to the caller cb.
Next, the caller has to free it when is not needed anymore or pass it
up to the stack.
