Instead of using a best-fit algorithm to determine which part
of the VMID 0 address space to use for GART, always use the low
address range.

A subsequent commit will use this to map the VCPU BO in GART
for the VCE1 IP block.

Split this into a separate patch to make it easier to bisect,
in case there are any errors in the future.
