sysinfo: update QR payload data sources and output 

Read the QR serial number from /proc/device-tree/serial-number and the
MAC address from the U-Boot ethaddr environment variable.

Include digi,drm-ic in the QR payload only when present, and update the
console output and provisioning message accordingly.
