eea9f99397 drivers: Remove CONFIG_TEGRA_VIRTUALIZATION
Remove CONFIG_TEGRA_VIRTUALIZATION so that virtualization is always
enabled for drivers. This permits the same drivers to work on bare-metal
Linux machines as well as virtual Linux machines.

deffbf24ab virt: tegra: Ensure functions stubs are defined
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.

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.
