hwsim: change radio Create() to take a dictionary 

The Create() API was limited to only taking a Name and boolean
(for p2p enabling). The actual hwsim nl80211 API can take more
attributes than this (which are actually utilized when creating
from the command line). To get the DBus API up to the same
functionality the two arguments in Create were replaced with
a single dictionary. This allows for extending later if more
arguments are needed.
