Add a new host1x-nvhost driver that provides an nvhost interface for
the upstream Linux host1x driver so that downstream drivers that use
this interface can be supported on upstream.
Note that some of the nvhost function prototypes are moved from their
default header file to the include/linux/nvhost.h header file so
simplify building with upstream and downstream kernels.
