Release Linux 4.9.2-openpower1
This moves from the 4.4 based kernel series to the newer long term
support kernel, Linux 4.9.
To make the move we regenerate the kernel defconfig for the new kernel.
We still have three out of tree patches. This commit makes the following
changes:
* Drops 5 of our out of tree patches
* Two remain for XHCI kexec issues
* One remains for VGA handover
We also update bnx2x firmware version for newer kernel driver, which
means modify the firmware whitelist.

+Subject: [PATCH 3/4] xhci: do not halt the secondary HCD
+
+We can't halt the secondary HCD, because it's also the primary HCD,
+which will cause problems if we have devices attached to the primary
+HCD, like a keyboard.
