mb/google/brya: Correct Ti50 EC-is-trusted logic
With Cr50, the GPIO EC_IN_RW is used to determine whether EC is trusted. However, With the switch to Ti50, 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.
