mb/google/corsola: Correct EC-is-trusted logic
With Cr50, the GPIO EC_IN_RW_ODL is used to determine whether EC is trusted. However, with Ti50 where corsola has been switched to, it is determined by Ti50's boot mode. If the boot mode is TRUSTED_RO, the VB2_CONTEXT_EC_TRUSTED flag will be set in check_boot_mode(). Therefore in the Ti50 case get_ec_is_trusted() can just return 0. The current code of get_ec_is_trusted() only checks the GPIO, which causes the EC to be always considered "trusted". Therefore, correct the return value to 0 for TPM_GOOGLE_TI50.
