    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.
