nvc0: create screen fence objects with coherent attribute
This is required on non-coherent architectures to ensure the value of
the fence is correct at all times. Failure to do this results in the
display freezing for a few seconds every now and then on Tegra.
The NOUVEAU_BO_COHERENT is a no-op for coherent architectures, so behavior
on x86 should not be affected by this patch.
Also bump the required libdrm version to 2.4.62, which introduced this
flag.
