ide: merge ->fixup and ->quirkproc methods

* Assign drive->quirk_list in ->quirkproc implementations:
  - hpt366.c::hpt3xx_quirkproc()
  - pdc202xx_new.c::pdcnew_quirkproc()
  - pdc202xx_old.c::pdc202xx_quirkproc()

* Make ->quirkproc void.

* Move calling ->quirkproc from do_identify() to probe_hwif().

* Convert it821x_fixups() to it821x_quirkproc() in it821x.c.

* Convert siimage_fixup() to sil_quirkproc() in siimage.c, also remove
  no longer needed drive->present check from is_dev_seagate_sata().

* Convert ide_undecoded_slave() to accept 'drive' instead of 'hwif'
  as an argument.  Then convert ide_register_hw() to accept 'quirkproc'
  argument instead of 'fixup' one.

* Remove no longer needed ->fixup method.
