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.

MCB aperture is already ioremapped in MC driver using
devm_ioremap_resource(). This doesn't allow other driver to ioremap
this aperture using devm_ioremap* calls.
mc-t26x driver need to access MCB aperture to get carveout info.
So, fix this by using just ioremap on aperture without using devm*
APIs.
Also, fix the carveout apertures.

The compiler option -Wmissing-prototypes is being enabled globally in
the upstream Linux kernel and this causes build failures. The build
failures occur because either the driver is missing an include file
which has the prototype or because the function is not declared
statically when it should be (ie. there are no external users).
Fix the various build failures that are seen when enabling
-Wmissing-prototypes.

Add support for mc-err driver on T264. Maintain driver similar to
current upstream mc-err driver, so that upstreaming diff for T264 would
be straight forward. Current IRQ handling logic is as follows:
- Read MCF int status from MCB
- Find out the MC channel responsible for generating error
- Read address register from that MC channel block to get the address
- Find out type of error from status register
Current implementation is as per the information received so far,
further updates will be made once HW team provide programming
guidelines.
