[PATCH v1 3/3] board: qualcomm: Remove SCSI scan from default preboot environment

Remove "scsi scan" from the preboot command sequence in the default
Qualcomm board environment. The SCSI scan command fails on eMMC-based
boot configurations, causing unnecessary boot delays and potential
error messages during the preboot phase.

This change improves boot reliability on platforms using eMMC storage
as the primary boot device.
