Subject: [PATCH AUTOSEL 5.4 27/28] drm/msm: Call msm_init_vram before binding the gpu

From: Craig Tatlor <ctatlor97@...il.com>

[ Upstream commit d863f0c7b536288e2bd40cbc01c10465dd226b11 ]

vram.size is needed when binding a gpu without an iommu and is defined
in msm_init_vram(), so run that before binding it.
