gpu: nvgpu: Disable compression for k6.1+

Browse Source 
dmabuf internals that nvgpu relies upon for storing meta-data for
compressible buffers changed in k6.1. For now, disable compression
on all k6.1+ kernels.

Additionally, fix numerous compilation issues due to the bit rotted
compression config. All normal Tegra products support compression
and thus have this config enabled. Over the last several years
compression dependent code crept in that wasn't protected under the
compression config.
