nvidia-oot: Fix ccflag for IVC legacy support

Browse Source 
The flag CONFIG_TEGRA_IVC_LEGACY_DISABLE was added so that it can be set
by an external Makefile that build the out-of-tree drivers. If this flag
is set by an external Makefile then the ccflags definition
'-DCONFIG_TEGRA_IVC_LEGACY_DISABLE' does not get set as expected and
builds fail. Fix this by setting the ccflag if the Make flag
CONFIG_TEGRA_IVC_LEGACY_DISABLE is set and not just for Linux v6.2+
kernels.
