Subject: [PATCH] ieee1275: implement FCP methods for WWPN and LUNs
This patch enables the fcp-targets and fcp-luns methods which are
responsible to get WWPNs and LUNs for fibre channel devices.

Patch-Mainline: no
Because Openfirmware returns invalid ihandler when it tries to open a disk
which his first partition is not a supported one by the firmware (Prep, FAT,
ISO), the grub needs to understand when it should open the disk in "raw mode",
appending a ":0" in the end of the device path.
Openfirmware is unable to open disk that contains a unknown first partition
(i.e it is not a PreP, Fat, ISO) ; We needed to open the disk in "raw mode" and
so Grub was required to take care of partitions and contents.
