Subject: [PATCH 5.4 073/122] crypto: ccp - Annotate SEV Firmware file names

From: Joerg Roedel <jroedel@...e.de>

commit c8671c7dc7d51125ab9f651697866bf4a9132277 upstream.

Annotate the firmware files CCP might need using MODULE_FIRMWARE().
This will get them included into an initrd when CCP is also included
there. Otherwise the CCP module will not find its firmware when loaded
before the root-fs is mounted.
This can cause problems when the pre-loaded SEV firmware is too old to
support current SEV and SEV-ES virtualization features.

Fixes: e93720606efd ("crypto: ccp - Allow SEV firmware to be chosen based on Family and Model")
