of_default_bus_match_table was not exported earlier, so it could only
be accessed by code compiled into the kernel. A new function
of_platform_default_populate() was added which uses
of_default_bus_match_table and this function is also exported. This way
it is possible to create a bus with the content of
of_default_bus_match_table and we can remove the hacks from bcma.

When p2p device interface gets deleted by deinitialising discovery
it will result in an event which removes the interface, but that is
also done by delete p2p interface code. This results in race
condition which sometimes results in lockup/crash. With this patch
the delete device interface will wait for the event (with timeout)
removing the possible race condition. Also on the stop device call
from cfg80211 the deinitialisation of the discovery device should
be avoided as it can result in a similar situation.
