4.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit d1518a1db31a25682ea09c4b135fa72d9883be42 upstream.
early_init gets called before atom asic init so on non-posted
cards, the vram type is not initialized.
