vboot_logic: Set VB2_CONTEXT_EC_TRUSTED in verstage_main
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.
