drm/nouveau/mmu/gp100: Remove unused/broken support for compression
From GP100 onwards it's not possible to initialise comptag RAM without
PMU firmware, which nouveau has no support for.
As such, this code is essentially a no-op and will always revert to the
equivalent non-compressed kind due to comptag allocation failure. It's
also broken for the needs of VM_BIND/Vulkan.
Remove the code entirely to make way for supporting compression on GPUs
that support GSM-RM.
