1c31e80d60 virt: tegra: Disable hypervisor driver for Linux v6.2+ 
Upstream Linux commit 4c1e0a97351a ("firmware: tegra: bpmp: Use
iosys-map helpers") updated the Tegra IVC driver to use the
iosys-map helpers for Linux v6.2. This causes the Tegra Hypervisor
driver build to fail. Temporarily disable the building of this
driver while this build issue is fixed. Stub functions are added to
permit other drivers that use this driver to build.

as platform driver since insertion of this module
is getting failed on native kernel due to
is_tegra_hypervisor_mode API failure since
hypervisor environment is missing, leading to
nvethernet module insertion causing the error
"Unknown Symbol tegra_hv_ivc_reserve".

WARNING: modpost: /home/mbhardwaj/kernel_only/out/
embedded-linux-generic-release/nvidia/kernel-rt_patches-nvidia-oot/
nvidia-oot/drivers/virt/tegra/tegra_hv.o (.exit.text+0x34): Section
mismatch in reference from the function cleanup_module() to the
function .init.text:tegra_hv_cleanup()
The function __exit cleanup_module() references a function __init
tegra_hv_cleanup(). This is often seen when error handling in the
exit function uses functionality in the init path. The fix is often
to remove the __init annotation of tegra_hv_cleanup() so it may be
used outside an init section.
