anv: enable sparse by default on i915.ko

Browse source 
On i915.ko we don't have the vm_bind ioctl, so sparse requires TR-TT.
Unfortunately, on gfx < 20 TR-TT is not compatible with non-render
queues, so we have to disable those when sparse is enabled. Notice
that although we don't have TR-TT for non-render queues on gfx >= 20,
vm_bind is the default, and it doesn't have this restriction.
