Subject: [PATCH 5.14 085/151] fpga: ice40-spi: Add SPI device ID table

From: Mark Brown <broonie@...nel.org>

commit 2a2a79577ddae7d5314b2f57ca86b44d794403d5 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 ID table.

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