drm/etnaviv: relax submit size limits

Browse Source 
commit e3d26528e083e612314d4dcd713f3d5a26143ddc upstream.

While all userspace tried to limit commandstreams to 64K in size,
a bug in the Mesa driver lead to command streams of up to 128K
being submitted. Allow those to avoid breaking existing userspace.
