vboot_reference is introducing a new field (ctx) to store the current boot mode in crrev/c/2944250 (ctx->bootmode), which will be leveraged in both vboot flow and elog_add_boot_reason in coreboot. In current steps of deciding bootmode, a function vb2ex_ec_trusted is required. This function checks gpio EC_IN_RW pin and will return 'trusted' only if EC is not in RW. Therefore, we need to implement similar utilities in coreboot. We will deprecate vb2ex_ec_trusted and use the flag, VB2_CONTEXT_EC_TRUSTED, in vboot, vb2api_fw_phase1 and set that flag in coreboot, verstage_main. Also add a help function get_ec_is_trusted which needed to be implemented per mainboard.
