PEL: Save the motherboard CCIN in the SRC

The CCIN field is from the CC keyword of the VINI record in the
motherboard VPD.

Save it in the first half of the second hex word of the SRC.

Also print this field when displaying the SRC section, but only for SRCs
created by this code, which it knows by checking the first 2 characters
of the ASCII string.
