brcmfmac: Update netdev configuration in wiphy for p2p.

Wiphy object holds information about possible netdev
combinations which can be supported. This needs updating for
p2p device. Also p2p device netdev has wrong 80211 iftype.
Limit the change interface support to match the netdev
configuration/combination possibilities.
