etnaviv: use TX_SEAMLESS_CUBE to determine seamless cubemap support

Browse source 
I have no idea why the HWDB includes two distinct bits that seem to
relate to seamless cubemap support. However, the only cores where
both bits disagree are NPUs (which don't have any samplers) and the
GC880, which is currently special cased in the driver.

Use TX_SEAMLESS_CUBE to determine seamless cubemap support, which
seems to accurately reflect the real support status.
