Sysinfo prints the model obtained from device tree, checkboard() take info from hardware and tdx_checkboard() use the model retrieved by toradex config block. Remove the print from checkboard() function because the model obtained from toradex config block is the most complete. If toradex config block is missing the model info from device tree is enough.
