video: tegra: nvmap: Update carveout name

Browse Source 
CBC carveout is not the correct carveout name, rather compression
carveout is the correct name. Compresssion carveout is used to store the
gpu compressible buffers. While the comptags and other metadata related
to these buffers will be stored in CBC carveout which is a GSC carveout
not created/maintained by nvmap. Hence update carveout naming.
