danevo: add 2p card reader (#902)

## Link to GitHub Issue or related Pull Request, if one exists
Fixes #901

## Description of change
This adds 2p card reader support to DanEvo. The cab only has one keypad
but this is not a configuration spice supports today so spicecfg will
show two keypads.

## Testing
2p card was recognized in test mode. No other testing performed.
