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.

Instead of using kernel version checks in the Tegra DRM driver for the
tegra_fb_ops structure, just check if the appropriate definition is
defined and if so use it. This fixes building the Tegra DRM driver
against some 3rd party kernels that include backports from upstream.
Note that this also aligns the driver closer to the upstream code by
using the same definitions that the upstream driver uses.

In Linux v6.2, the Tegra IVC driver was updated to support iosys-map and
this breaks building some of the out-of-tree drivers for Linux v6.2+
kernels. In Linux v6.3, the GPIO OF APIs were removed and this breaks
building some of the out-of-tree drivers that use these legacy APIs. For
now the broken drivers are not built for these corresponding kernels.
Instead of checking the kernel version in the Makefile for the
corresponding broken driver, move the kernel version checking to the
top-level Makefile and add CONFIG definitions that can be used the
various Makefiles.
This is also needed for working with 3rd party Linux kernels that may
have upstream backports and need to set these CONFIG variables for their
Linux kernel.

When compiling the out-of-tree audio drivers against a kernel that does
not have CONFIG_SND_SOC enabled, the build fails because the various
snd_soc_xxx functions are not exported by the kernel. Update the
out-of-tree Makefile to only build the Tegra ASoC drivers if
CONFIG_SND_SOC is enabled. Note that CONFIG_SOUND is enabled if
CONFIG_SND_SOC is enabled so it is not necessary to check for both.

Determining whether the header file iosys-map.h is present in the kernel
is currently determine by kernel version. However, for Linux v5.15,
iosys-map.h has been backported in order to support simple-framebuffer
for early display. Therefore, we cannot rely on the kernel version to
indicate whether iosys-map is present. This is also true for 3rd party
Linux kernels that backport changes as well. Fix this by adding a
compile time flag, that will be set accordingly by the conftest script
if this header is present.
