I managed to set up the p2p interface by recompiling the kernel with
CONFIG_BRCMDBG and loading the brcmfmac module with p2pon=1.

I had a discussion some month ago with Hante Meulemann about setting up
the p2p interface. This is one of his replies:

    "For what I can see from the log is that we don’t get the event from
    the FW indicating that the p2p interface was created. This probably
    means that there is a bug in this FW for this device. I need to discuss
    this to see how much priority we can give this. The best option for you
    for the moment is to use the legacy method with the 'p2pon=1' command."
