Generate a MAC address based on the cpuid available in the efuse block: Use the first 6 byte of the cpuid's SHA256 hash and set the locally administered bits. Also ensure that the multicast bit is cleared.
The MAC address is only generated and set if there is no ethaddr present in the saved environment.

Changes in v3: - uses uclass_get_device_by_driver() to ensure we don't pick up the wrong misc-device
Changes in v2: - added derivation of ethaddr from cpuid
