delbin_npcx796fc: Initial EC image

Create the initial EC image for the delbin_npcx796fc variant by
copying the delbin reference board EC files into a new directory
named for the variant.

(Auto-Generated by create_initial_ec_image.sh version 1.3.0).

+ * Operation status which contains the FET status bits.

+ * The assumption for battery types supported is that the charge/discharge FET
