[PATCH] Mandatory install device check for PowerPC

[Avnish Chouhan]

This patch adds a check on install_device while installing grub for PowerPC.
If install_device is not mentioned in grub2-install, the error will be thrown.
Running grub2-install on PowerPC without the install_device may 
result in boot corruption.
