gpu: ion: Add check for cached kernel mappings An ION content protection heap should not allow cached kernel space mapping for a heap that is protected. Also, ION should not allow a heap that has outstanding cached kernel space mappings to be protected. These checks will ensure that the kernel doesn't try to access memory that is locked down and it cannot access.
