ec/dasharo/ec: Add initial copy of ec/system76/ec
Initial commit is a copy of ec/system76/ec from tag v24.02.1 (commit 0a280ff7) with string changes. Dasharo-specific features will be added in subsequent commits, similar to how Librem EC support was added in changes 52390 and 52391. Change-Id: Ic7c3d9413488026548514963eb78accc28e41e06 Signed-off-by: Michał Kopeć <michal.kopec@3mdeb.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/82671 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Felix Singer <service+coreboot-gerrit@felixsinger.de>
