2a938c39ec drm/tegra: Implement buffer object cache
This cache is used to avoid mapping and unmapping buffer objects
unnecessarily. Mappings are cached per client and stay hot until
the buffer object is destroyed.

d802ae96a7 drm/tegra: Implement correct DMA-BUF semantics
DMA-BUF requires that each device that accesses a DMA-BUF attaches to it
separately. To do so the host1x_bo_pin() and host1x_bo_unpin() functions
need to be reimplemented so that they can return a mapping, which either
represents an attachment or a map of the driver's own GEM object.

f6e4773a0d UPSTREAM: gpu:host1x: Split up client initalization and registration
In some cases we may need to initialize the host1x client first before
registering it. This commit adds a new helper that will do nothing but
the initialization of the data structure.

At the same time, the initialization is removed from the registration
function. Note, however, that for simplicity we explicitly initialize
the client when the host1x_client_register() function is called, as
opposed to the low-level __host1x_client_register() function. This
allows existing callers to remain unchanged.

f6a7adab82 UPSTREAM: gpu:host1x: Add early init and late exit callbacks
These callbacks can be used by client drivers to run code during early
init and during late exit. Early init callbacks are run prior to the
regular init callbacks while late exit callbacks run after the regular
exit callbacks.

54584c92ca gpu: host1x: Clean-up build for Host1x
Trivial clean-up for building Host1x by ...

1. Removing the Kconfig file because this is not needed for building
   as an external module and we only plan to build this as an external
   module.
2. Moving both 'host1x-next.h' header files under the Host1x source
   directory so that we don't need to pass the path for finding the
   header when building Host1x as an external module.
3. Remove the 'CONFIG_TEGRA_HOST1X_NEXT' variable because we always
   build Host1x as a module.
