  SVN rev 200746 on 2009-12-20 01:44:47Z by marius
  
  MFC: r200482, r200485
  
  o Properly support M5229 revision 0xc7 and 0xc8:
    - These revisions no longer have cable detection capability.
    - The UDMA support bit of register 0x4b has been dropped without an
      replacement.
    - According to Linux it's crucial for working ATAPI DMA support to
      also set the reserved bit 1 of regsiter 0x53 with these revisions.
  o Only set ATA_CHECKS_CABLE for chip versions that actually support
    cable detection, i.e. neither for ALI_OLD nor for ALI_NEW revisions
    >= 0xc7.
