[PATCH v2] gpio: 74x164: Add SPI device ID table

[Mark Brown <broonie@xxxxxxxxxx>]

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")

v2: Fix typos in the device names, sorry.
