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.
