[PATCH 1/3] ice: add support for 3k signing DDP sections for E825C

[Michael Reed]

From: Grzegorz Nitka <grzegorz.nitka at intel.com>

BugLink: https://bugs.launchpad.net/bugs/2114785

E825C devices shall support the new signing type of RSA 3K for new DDP
section (SEGMENT_SIGN_TYPE_RSA3K_E825 (5) - already in the code).
The driver is responsible to verify the presence of correct signing type.
Add 3k signinig support for E825C devices based on mac_type:
ICE_MAC_GENERIC_3K_E825;
