b06375f360 gpu: host1x: Set waiter output reference within lock
With the new fence implementation, we need to assign the reference
within the lock. Otherwise, it can happen that the waiter may get
signaled before the pointer has been set, and the fence implementation
will try to call intr_put_ref with a NULL pointer.

cc5bcef3f6 gpu: host1x: Add upstream host1x driver
Add the upstream host1x driver with the 'Host1x/Tegra UAPI' series [0]
applied. This driver will be built as an external module for use with
the NVGPU driver on upstream Linux kernels.

The following modifications have been made to the series posted upstream
1. Update the Makefile to always build the driver as a module
2. Remove the tests to see if CONFIG_DRM_TEGRA_STAGING is enabled
3. Rename the include/linux/host1x.h to include/linux/host1x-next.h to
   avoid conflicts with upstream headers when building as an external
   module.
4. Rename the include/uapi/linux/host1x.h to
   include/uapi/linux/host1x-next.h to avoid conflicts with upstream
   headers when building as an external module.
5. Rename the module that is built to be host1x-next.ko instead of
   host1x.ko to avoid any depmod conflicts with the upstream driver.
