Subject: [PATCH] driconf: disable allow_rgb16_configs for SPECviewperf

Commit f2aaa9ce00f added 16 bpc unorm display formats gated behind the flag
allow_rgb16_configs driconf option, defaulting to true.

This causes SPECviewperf's maya_06 viewset to fail. Disabling
allow_rgb16_configs for SPECviewperf alongside the existing
allow_rgb10_configs workaround.

Fixes: f2aaa9ce00f ("dri,gallium: Add support for RGB[A]16_UNORM display formats.")
