hpt366: remove ->init_setup

* Split off hpt{374,371,366}_init() helper from init_setup_hpt{374,371,366}().

* Merge init_setup_{374,372n,371,372a,302,366}() into hpt366_init_one().

While at it:

* Use "HPT36x" name for HPT366/HPT368 chipsets.

* Add .chip_name to struct hpt_info and use it to set set d->name.

* Convert .max_ultra in struct hpt_info to .udma_mask and use it to set
  d->udma_mask.

* Fix hpt302 to use HPT302_ALLOW_ATA133_6 define.

* Change HPT366/HPT374 interrupt fixup message from KERN_WARNING to KERN_INFO.

* Use the second hpt366_chipsets[] entry for HPT37x chipsets using HPT36x PCI
  device ID and fix .enablebits/.host_flags for HPT36x hpt366_chipsets[] entry.

* Bump driver version.
