video: tegra: nvmap: Switch to configurable granule size
...
In compression carveout, granule size should be configurable via device
tree. Earlier code was written by considering granule size of 2MB,
update the code to use configurable granule size read from DT.

video: tegra: nvmap: Update carveout name
...
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.

video: tegra: nvmap: Add CBC carveout support
...
- Add CBC carveout suport in nvmap.
- Chunk size for CBC is 2MB, hence each bit from bitmap for CBC carveout
indicate 2MB physically contiguous chunk.
- In case of allocation from CBC, first try to allocate the entire chunk
in physically contiguous manner, if it's not possible then allocate in
chunks of 2MB. All page pointers to these chunks will be stored in
nvmap_handle struct.
- Modify all other operations like vmap, kmap, mmap as per the above
restrictions.
