Subject: [PATCH AUTOSEL 5.10 1/4] usb: host: max3421-hcd: Add missing spi_device_id table

From: Alexander Stein <alexander.stein@...lbox.org>

[ Upstream commit 41d5e3806cf589f658f92c75195095df0b66f66a ]

"maxim,max3421" DT compatible is missing its SPI device ID entry, not
allowing module autoloading and leading to the following message:
 "SPI driver max3421-hcd has no spi_device_id for maxim,max3421"

Fix this by adding the spi_device_id table.
