9410c97b90 crypto: tegra: Fix build for Linux v6.11 
In Linux v6.11, the 'platform_driver' structure 'remove' callback was
updated to return void instead of 'int'. Fix the build for Linux v6.11
by simply removing the 'remove' callback for the Tegra SE KDS driver
because it does nothing.

d5391a25ab drivers: Enable -Wmissing-prototypes 
The compiler option -Wmissing-prototypes is being enabled globally in
the upstream Linux kernel and this causes build failures for various
drivers. 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 and enable -Wmissing-prototypes to
prevent any new instances from occurring. Note that the only driver that
is not fixed at the moment is rtl8822ce due to large number of failures
and so build this with '-Wno-missing-prototypes' for now, which is not
different to how it was being compiled prior to this change.
