ide: move ide_pio_cycle_time() to ide-timings.c
All ide_pio_cycle_time() users already select CONFIG_IDE_TIMINGS
so move the function from ide-lib.c to ide-timings.c.
While at it:
- convert ide_pio_cycle_time() to use ide_timing_find_mode()
- cleanup ide_pio_cycle_time() a bit
There should be no functional changes caused by this patch.
