[neo] Every access to GPIO bank B has to go through the shadow code

    - Any setting of any PIN on bank B will undo the LED setting.
      Introduce neo1973_gpb_set_pin to set the PIN in a way not losing
      the LED or any other shadowed setting.
    - Update users of GPBXY for gta01 and gta02.
