can't boot to disk from netboot on power8

[Mathieu Trudel-Lapierre]

[Impact]
This affects users of POWER systems booting from the network in an attempt to boot the system on disk via grub2, as is typically done in MAAS-based installs and system provisioning.

[Test case]
- Attempt to boot the system from the network to grub; in order to boot off the local disk.
-or-
- Attempt to fully provision a system using MAAS, from starting the installer to rebooting to the installed system using the MAAS features to Deploy and Acquire a system.

[Regression Potential]
This modification introduces new work to be done by grub to spin up and detect disks from the ofdisk module; in turn, this may increase delay in booting to the point of reaching a timeout (failure to boot). Possible regressions might include booting to an incorrect device due to more devices being available for grub to peruse, which could mean changes to the device numbering due to more devices being detected (systems failing to boot following the update due to device numbering changes, rendering working grub.cfg configs ineffective).

--

It should be possible to use BOOTP to boot from the network, and then tell a PowerVM node to local boot via grub2.

Unfortunately, this fails as it cannot see the disks/partitions.

Upstream has a fix committed to solve the problem:
http://git.savannah.gnu.org/cgit/grub.git/commit/?id=c899d9f42c543939abc92d79c9729d429740492e

This patch should be cherry-picked.
