The calibration blob for a chip is normally stored in SROM and loaded internally by the firmware. However, Apple ARM64 platforms instead store it as part of platform configuration data, and provide it via the Apple Device Tree. We forward this into the Linux DT in the bootloader. Add support for taking this blob from the DT and loading it into the dongle. The loading mechanism is the same as used for the CLM and TxCap blobs.
