There are three changes here:
- Fix `rp2_pio_print` to use `pio_get_index()` too, since it had its own
copy of the ternary expression.
- Remove a ternary from `rp2_pio_state_machine` and calculate it from
`pio_get_index`.
- Remove a ternary on `GPIO_FUNC_PIO0` vs `GPIO_FUNC_PIO1`. These
constants are sequentially ordered so we can calculate them too.
