[libata] support for > 512 byte sectors (e.g. 4K Native)
This change enables my x86 machine to recognize and talk to a
"Native 4K" SATA device.
When I started working on this, I didn't know Matthew Wilcox had
posted a similar patch 2 years ago:
http://git.kernel.org/?p=linux/kernel/git/willy/ata.git;a=shortlog;h=refs/heads/ata-large-sectors
Gwendal Grignou pointed me at the the above code and small portions of
this patch include Matthew's work. That's why Mathew is first on the
"Signed-off-by:". I've NOT included his use of a bitmap to determine
512 vs Native for ATA command block size - just used a simple table.
And bugs are almost certainly mine.
Lastly, the patch has been tested with a native 4K 'Engineering
Sample' drive provided by Hitachi GST.
