meta-phosphor: npcm8xx.bbclass: support sign images feature
Add sign images feature according customer's requirement.
Set "SECURED_IMAGE" to "True" and enable sign images feature.
When sign images feature be enabled. Use default keys to sign
images if customer didn't point their own local keys path.
Note: "SECURED_IMAGE" default is "True".
Tested:
Use default keys sign:
That will use default path and keys from igps to sign.
Use local keys sign:
That will use local path and keys to sign.
When KEY_FOLDER and KEY definition both are valid.
However, when KEY_FOLDER and KEY definition are invalid either,
that will output sign images failed then stop build full images.
Tested: build pass and boot up successfully with signed
