device/trezor: passphrase entry on host

Browse source 
- simple device callback object added. Device can request passphrase/PIN entry via the callback or notify user some action is required
- callback is routed to wallet2, which routes the callback to i_wallet_callback so CLI or GUI wallets can support passphrase entry for HW tokens
- wallet: device open needs wallet callback first - passphrase protected device needs wallet callback so user can enter passphrase
