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.
