video: tegra: nvmap: support clean only dirty option on write back
Modify cache maintenance operation to specify option whether to
clean only dirty pages or all pages from cache within the
specified range. This can help unnecessary overhead of cleaning
pages which are not dirty as well.
clean only dirty option is preferred for user space accesses since
dirty pages can be tracked only for those.
For kernel, since there is no mechanism to find out the dirty pages,
this option cannot be used.
