drm/amdgpu/vce1: Check if VRAM address is lower than GART.

Browse source

Previously, I had assumed this was not possible
so it was OK to not handle it, but now we got a report
from a user who has a board that is configured this way.

When the VCPU BO is already located in a low 32-bit address
in VRAM (eg. when VRAM is mapped to the low address space),
don't do the workaround.
