video: tegra: nvmap: move nvmap to DT

This patch migrates nvmap to the device tree. The legacy path
is retained; i.e the path that loads the VPR sizes from the
kernel's command line arguments.

This patch also renames the nvmap device and driver to
'nvmap-carveouts'. This works better with the device tree
nomenclature.
