80828001d5 gpu: host1x: Deduplicate hardware headers
Host1x class information and opcodes are unchanged or backwards
compatible across SoCs so let's not duplicate them for each one
but have them in a shared header file.

At the same time, add opcode functions for acquire/release_mlock.

9e4475c800 gpu: host1x: Program context stream ID on submission
Add code to do stream ID switching at the beginning of a job. The
stream ID is switched to the stream ID specified by the context
passed in the job structure.

Before switching the stream ID, an OP_DONE wait is done on the
channel's engine to ensure that there is no residual ongoing
work that might do DMA using the new stream ID.

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.
