Full passphrase support in newest Trezor firmwares (1.9.0 and 2.3.0)

[tsusanka]

We have done some modifications regarding how passphrase is communicated between Trezor and the host.

Please upgrade the trezor-connect dependency of your application to latest (8.1.1 atm), otherwise your users won't be able to enter passphrase on the device (on Trezor T).

Thanks!
