ramips: Cudy X6 fixes / improvements
- Correct WiFi MACs, they didn't match oem firmware
- Move nvmem-cells to bdinfo partition and remove &bdinfo reference
- Add OEM device model name R13 to SUPPORTED_DEVICES
This allows sysupgrading from Cudy's OpenWrt fork without force
- Label red_led and use it during failsafe mode and upgrades
MAC addresses as verified by OEM firmware:
