Use external blob otpcmd.bin to replace the 0xff filled OTP programming command block to create a firmware image that provisions the OTP on first boot. This otpcmd.bin is generated from the customer keys using steps described in the meta-iot2050 integration layer for the device. Based on original patch by Baocheng Su.
