Subject: [3.6-rc3 regression] sata_mv cannot get optional clkdev breaking boot on QNAP TS-119P+

My Kirkwood-based QNAP TS-119P+ boots fine with the 3.5 kernel.  With
3.6-rc2 and 3.6-rc3 however sata_mv complains:

sata_mv sata_mv.0: cannot get optional clkdev
sata_mv sata_mv.0: slots 32 ports 2

and then the kernel grinds to a halt with no further messages.

Full boot log from 3.6-rc3 appended below.  .config available upon
request, but this is a non-DT kernel.
