Update the Tegra DRM to align with Linux v6.15-rc3. In Linux v6.15-rc3,
the arguments of the 'mode_valid' function pointer of the
drm_connector_helper_funcs structure and the 'atomic_async_check'
function pointer of the drm_plane_helper_funcs structure were updated.
Add conftest tests to detect these updates and make the necessary
changes to the Tegra DRM driver.

Adding the build flag '-Werror=declaration-after-statement' to prevent
mixing variable definitions within the body of code. Ideally, we would
enable this for all kernels, but in the latest upstream Linux kernels
this flag has been removed from the kernel build to allow for scope
based declarations in some contexts. However, even in the upstream
kernel declaring variables at the start of the scope is recommended. Add
this flag for noble kernels to ensure that this recommendation is
followed for OOT drivers.

Fix this by declaring the necssary variables at the beginning of the

Remove power management ops from the host1x bus-side DLA driver. The host1x
bus-side driver is a virtual device and should not directly access hardware.
PM ops should only be used in the platform device driver.
This fixes suspend/resume test failure when tegra-drm is loaded without any
enabled engines under host1x node.

- The VI is allowed to access the whole of the Guest VM currently as it
is a stage-2 SMMU device. Hence it can read and write to any memory.
This may lead to breach of confidentiality and integrity. In order to
restrict the VI from accessing the whole VM, a mempool is being created
by HV that would restrict access to VI to just the mempool memory.
- In nvmap, we have some special rules for IVM carveout like if user
specify IVM carveout to allocate from, then if first IVM carveout does
not have sufficient memory then nvmap tries to allocate from next IVM
carveout. We don't want these rules applicable for VI mempool heap,
hence only carveout initialization part would remain similar to IVM
carveouts but rest of the operations would be performed normally like
any other carveout.
- Add DT binding doc for VI-carveout.

HW takes care performing the TSO handling. Also optimized the checks
