The firmware will sent an event message when bc/mc traffic should
be sent to the device using credit mechanism.

In brcmf_rx_frames() the call to brcmf_fweh_process_skb() could
change the ifidx using information in the event data. This is
only different to the BDC ifidx for IF ADD event. However, the
creation of the new interface is deferred to event worker so
it does not exist. After brcmf_fweh_process_skb() it is only
used to set statistics.

Currently, adding a new event requires modification in two source
files. Use macro definition to have one place and have better
maintainability.

Handling of firmware event has been reworked into a seperate
code file. The change is needed as firmware event can be received
in interrupt context. Decoupling of the event handling has been
lowered to allow event processing to sleep.
