[PATCH 4.5 027/124] drm/amdgpu/gmc: move vram type fetching into sw_init

[Greg Kroah-Hartman]

4.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deuc...@amd.com>

commit d1518a1db31a25682ea09c4b135fa72d9883be42 upstream.

early_init gets called before atom asic init so on non-posted
cards, the vram type is not initialized.
