Found it :-) It was the missing reset pulse.

I've attached two patches to choose from:

- fix-wlan-must-reset.patch is minimally invasive

- fix-wlan-share-bringup.patch does only the pin configuration in
  gta02_wlan_probe and shares the code of gta02_wlan_write for the
  rest. This introduces potential brief glitches on CHIP_PWD and
  WLAN_nRESET, but they shouldn't really matter.
