From: Stefan Eichenberger stefan.eichenberger@toradex.com

The Toradex configuration block is stored in the first boot partition of the eMMC. After reading the configuration block, U-Boot switches back to the user partition. Currently, this operation always targets mmc device 0, even when the configuration block is stored on mmc device 2.

This patch addresses the issue by switching the mmc device set in CONFIG_TDX_CFG_BLOCK_DEV to the user partition, rather than using the hardcoded device 0.
