[sw, tock] Use device specific configuration
Earlgrey can be run on different devices that may require different
initialisation parameters.
This change:
* Adds device specific configurations.
* Adds infrastructure to choose a configuration.
For the available options, see boards/opentitan/Cargo.toml. The option
to build for a specific device can be passed through the TOCK_FEATURES
environment variable. For example, "TOCK_FEATURES=device_verilator".
If TOCK_FEATURES is not specified, tock will be built for fpga by default.
NOTE: there might be a better way to request specific device than an
environment variable, however it is good enough as a first step
and can be improved in follow-up PRs.
