wlcore: remove wl12xx_platform_data

Browse Source 
Now that we have wlcore device-tree bindings in place
(for both wl12xx and wl18xx), remove the legacy
wl12xx_platform_data struct, and move its members
into the platform device data (that is passed to wlcore)

Davinci 850 is the only platform that still set
the platform data in the legacy way (and doesn't
have DT bindings), so remove the relevant
code/Kconfig option from the board file (as suggested
by Sekhar Nori)

Since no one currently uses wlcore_spi, simply remove its
platform data support (DT bindings will have to be added
if someone actually needs it)

help
The wl1271 daughter card for AM18x EVMs is a combo wireless
connectivity add-on card, based on the LS Research TiWi module with
Texas Instruments' wl1271 solution.
Say Y if you want to use a wl1271 expansion card connected to the
AM18x EVM.
