Given that:
* hpt366.c::hpt3xx_intrproc() is the only user of hwif->intrproc
* hpt366.c::hpt3xx_quirkproc() sets drive->quirk_list to 1 for quirky drives
which is a value unique to hpt366 host driver
we can remove hwif->intproc and just check for drive->quirk_list == 1
in ide_do_request().

Handling of quirky drives (problems with nIEN) by hpt366 and pdc202xx_*
looks suspicious... are the problems really dependent on the host type
(thus hwif->quirkproc and ->quirk_list == 1/2)? Shouldn't we just handle
quirky drives in the same way in the core IDE code regardless of the host
driver being used (of course using hwif->maskproc where needed)?
