Subject: [PATCH 5.15 800/917] mfd: sprd: Add SPI device ID table

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

[ Upstream commit c5c7f0677107052060037583b9c8c15d818afb04 ]

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")
