[GIT PULL] libata fixes for v4.11-rc6

[Tejun Heo]

Hello, Linus.

Two libata fixes.  One to disable hotplug on VT6420 which never worked
properly.  The other reverts an earlier patch which disabled the
second port on SB600/700.  There were some confusions due to earlier
datasheets which incorrectly indicated that the second port is not
implemented on both SB600 and 700.

Thanks.
