In Linux v6.11, the 'platform_driver' structure 'remove' callback was
updated to return void instead of 'int'. Update the Tegra264 memory
drivers as necessary to ensure that they can be built for Linux v6.11+
kernels.
The mem-qual driver is missing the vmalloc.h header file and this also
causes the build to fail for Linux v6.10+ kernels to fail.
Finally, remove the version.h file from the mem-qual driver as this is
not needed.

In Linux v6.4, the module pointer argument is removed from the
class_create() function. Add a test to the conftest script that checks
if this argument for the class_create() function has been removed and
use the definition created by conftest to select which version of the
function is used.

Add a loadable module for mem-qual STG IP client.
- This driver exposes following device nodes under /dev.
qualdev-0, qualdev-1, qualdev-2, qualdev-3, qualdev-4
- This driver provides 2 ioctls, one is to alloc a buffer and create
IOVA for it by mapping the buffer into the IOVA space of the respective
device.
- Second ioctl is to free the IOVA mapping and pages associated with the
buffer.
- Users of this driver will open the mem qual device node and then call
the first ioctl with size of the buffer as input during init time and
receive the IOVA.
- During deinit time, users will call the second ioctl with the IOVA as
input and the ioctl will free the IOVA mapping and buffer.
