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.

When building the out-of-tree drivers with virtualization support
disabled, symbols for some of the virtualization functions are not found
...
nvgpu: Unknown symbol tegra_hv_mempool_unreserve (err -2)
nvgpu: Unknown symbol is_tegra_hypervisor_mode (err -2)
nvgpu: Unknown symbol tegra_hv_mempool_reserve (err -2)
nvhost_pva: Unknown symbol is_tegra_hypervisor_mode (err -2)
mc_utils: Unknown symbol is_tegra_hypervisor_mode (err -2)
mc_utils: Unknown symbol is_tegra_hypervisor_mode (err -2)
Update the hv-ivc.h header to ensure that these function stubs are
defined when virtualization support is disabled and only build the
hv-ivc driver if virtualization is enabled.
Finally, move populating the ccflags to the top-level Makefile and use
the subdir-ccflags directive to ensure the ccflags are passed to all
sub-directories.

The option CONFIG_TEGRA_FUSE_UPSTREAM is not needed any longer because
we always want to enable this for Linux v5.15. Therefore, remove this
option completely.
The function tegra_fuse_control_read() is not used anywhere and so we
can also remove this too.

Starting with Linux kernel v5.17, the 'slave_id' member is removed from
the DMA Engine 'dma_slave_config' structure. Building the Tegra Safety
Audio driver against Linux v5.17, v5.18 and v5.19 breaks because this
filed is not defined. There are already comments in the driver to not
used the 'slave_id' field and move to using device-tree to get this
information. For now, fix the build by not using the 'slave_id' field
for Linux v5.17+.

Build errors seen in following contexts with kstable:
- The 'non_legacy_dai_naming' flag is not available in struct
'snd_soc_component_driver' in v6.0. Instead it is replaced
with flag 'legacy_dai_naming' and default value works fine.
To fix build error on kstable exclude the removed flag for
kernel v6.0 onward.
- Signature of snd_soc_card_jack_new() has changed in v5.19
which drops struct 'snd_soc_jack_pins' related members. These
were unused for Tegra and is safe to just update the funcion
call. Fix this by using correct function signature based on
kernel version checks.
With above fixed now, remove workaround from Makefile and enable
Audio OOT driver builds again with kstable.

All build errors have been now addressed by previous commits in the
series. Now enable OOT drivers build. To do so, update top level
makefile to include drivers path and update the internal makefile
to build individual drivers.
Some of the AHUB drivers are already upstreamed and are part of
v5.15 core kernel. But presently the drivers are copied to provide
full feature set. To differentiate core modules from OOT modules
the *.ko files here use "oot" string.
