ide: remove ->INS{W,L} and ->OUTS{W,L} methods

Browse Source 
* Use ins{w,l}()/outs{w,l}() and __ide_mm_ins{w,l}()/__ide_mm_outs{w,l}()
  directly in ata_{in,out}put_data() (by using IDE_HFLAG_MMIO host flag to
  decide which I/O ops are required).

* Remove no longer needed ->INS{W,L} and ->OUTS{W,L} methods (ide-h8300,
  au1xxx-ide and scc_pata implement their own ->{in,out}put_data methods).

There should be no functional changes caused by this patch.
