PATCH 1/1 crypto: ccp: Annotate SEV Firmware file names

From: Joerg Roedel <[email protected]>

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.
