[PATCH 1/2] offb: Fix bug in calculating requested vram size

From 448820776363da565f221c020f4ccb3c610faec3 Mon Sep 17 00:00:00 2001

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Date: Wed, 14 Dec 2011 16:52:02 +1100
Subject: 

We used to try to request 8 times more vram than needed, which would
fail if the card has a too small BAR (observed with qemu).
