Change in coreboot[master]: vboot: Fix wrong algorithm in TCPA log for BOOT_MODE

by Werner Zeh (Code Review)

Werner Zeh has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/35645 ) Change subject: vboot: Fix wrong algorithm in TCPA log for BOOT_MODE ...................................................................... vboot: Fix wrong algorithm in TCPA log for BOOT_MODE The hash algorithm for VBOOTs BOOT_MODE is fixed to sha1 but TCPA log uses sha256 as the name for the algorithm. This leads to an log entry with 20 bytes (sha1) while the algorithm is set to sha256 (which needs 32 bytes of hash). Fix it by using the matching algorithm name for BOOT_MODE.
