ide: move some bits from ide-timing.h to <linux/ide.h>
Move struct ide_timing and IDE_TIMING_* defines to <linux/ide.h> from drivers/ide/ide-timing.h. While at it: - use u8/u16 instead of short for struct ide_timing fields - use enum for IDE_TIMING_* There should be no functional changes caused by this patch.
