Check for OF support using IS_ENABLED(CONFIG_OF). This will enable the
compiler to eliminate dead code if OF support is disabled. With that in
place, the dummy implementation of bq24190_setup_dt() for non-DT setups
can be removed as the compiler will automatically discard the function
when appropriate.

The driver already uses the of_match_ptr() macro that evaluates to NULL
when DT is disabled, so defining an empty device table is unnecessary.
