[opentitantool] Minor refactors for transport interfaces

1. Define SPI Errors next to the SPI trait definition.
2. Define GPIO Erros next to the GPIO trait definition.
3. Express GPIO pins as strings.  Add the backend's default naming scheme
   for its pins.  A future PR will allow change this a bit more to permit
   user-defined pin-mappings.
4. Add some convenience methods to the GPIO trait to support bootstrap in
   a generic way.
5. Change the `gpio` command to use positional arguments where appropriate.

About the project

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
