> Currently autoloading for SPI devices does not use the DT ID table, it uses
> SPI modalises. Supporting OF modalises is going to be difficult if not
> impractical, an attempt was made but has been reverted, so ensure that
> module autoloading works for this driver by adding an id_table listing the
> SPI IDs for everything.
