Hmm strange, it seems to configure the wlan_rst pin. Maybe there
are variants with different WLAN module. But yeah, seems to be
unused.

That still leaves configuring all the dts users of the
pdata-quirks.c legacy_init_wl12xx() with proper dts before
removing it:

$ git grep legacy_init_wl12xx pdata-quirks.c
pdata-quirks.c:static void __init __used legacy_init_wl12xx(unsigned ref_clock,
pdata-quirks.c:static inline void legacy_init_wl12xx(unsigned ref_clock,
pdata-quirks.c: legacy_init_wl12xx(WL12XX_REFCLOCK_38, 0, 136);
pdata-quirks.c: legacy_init_wl12xx(0, 0, 177);
pdata-quirks.c: legacy_init_wl12xx(0, 0, 136);
pdata-quirks.c: legacy_init_wl12xx(WL12XX_REFCLOCK_38, 0, 149);
pdata-quirks.c: legacy_init_wl12xx(WL12XX_REFCLOCK_26, 0, 162);
pdata-quirks.c: legacy_init_wl12xx(WL12XX_REFCLOCK_38, 0, 145);
pdata-quirks.c: legacy_init_wl12xx(WL12XX_REFCLOCK_26,
pdata-quirks.c: legacy_init_wl12xx(WL12XX_REFCLOCK_38, 0, 53);
pdata-quirks.c: legacy_init_wl12xx(WL12XX_REFCLOCK_38, 0, 41);
pdata-quirks.c: legacy_init_wl12xx(WL12XX_REFCLOCK_38, 0, 31);

I guess Sekhar knows the da850 evm status the best. So up to
you guys if wl12xx is not being used on legacy da850.
