[PATCH 5.14 099/151] gpio: 74x164: Add SPI device ID table

From: Mark Brown <broonie@kernel.org>

commit be4491838359e78e42e88db4ac479e21c5eda1e0 upstream.

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 a SPI device ID table.

Fixes: 96c8395e2166 ("spi: Revert modalias changes")
