santvend: add an alternative way to get board rev
In case if gfplatdetect is not available in the system, extract a board
revision from /proc/cpuinfo.
Dear all, On Thursday, 4th September 2025, we will test the new disaster recovery environment. A disaster recovery test will take place between 4:00 PM and 6:00 PM CEST. Please refrain from making any changes, as they will be lost. Once testing is complete, the production environment will be restored. Thank you for your understanding.
