MFC r286448: Disable 32-bit PIO for 6Gbit/s Intel SATA controllers.
For some reason 32-bit PIO writes are not working on 6Gbit/s Intel SATA
ports, while 16/32-bit PIO reads and 16-bit PIO writes are working fine.
3Gbit/s ports on the same controllers have no this problem.
Workaround this by disabling 32-bit PIO for all Intel controllers that may
have 6Gbit/s ports. It halves PIO performance from 6MB/s to 3MB/s, but
who bother about speed of such rare and slow mode, which is also highly
discouraged by SATA specifications?

Before this change SYNCHRONIZE CACHE commands were executed exclusively,

also to perform additional initialization steps, such as setting the
