The event mailbox in wl18xx has a different
(non-compatible) structure.

Create common functions in wlcore to handle the
events, and call them from the chip-specific
event mailbox parsers.

This way, each driver (wl12xx/wl18xx) extracts
the event mailbox by itself according to its
own structure, and then calls the common
wlcore functions to handle it.

The scan APIs of 12xx and 18xx are totally different.
Use some common functions as much as possible (e.g.
for setting scan channels), but split scan.c into
chip-specific scan.c files, each implementing its
own scan mechanism.

(in other words - move most of the current wlcore's
scan.c into wl12xx, and implement a similar mechanism
in 18xx, according to the new api)

New wlcore ops are introduced in order to call the
chip-specific scan functions.

The template indices used for each scan (regular/scheduled)
are also different between the chips, so set the correct
indices used for each scan type after identifying the chip.
