soc/tegra: fuse: Define tegra194_soc_attr_group for Tegra241

Tegra241 SoC data uses tegra194_soc_attr_group, which is only defined
if config CONFIG_ARCH_TEGRA_194_SOC or CONFIG_ARCH_TEGRA_234_SOC or
both are enabled. This causes a build failure if both of these configs
are disabled and CONFIG_ARCH_TEGRA_241_SOC is enabled.

Define tegra194_soc_attr_group if CONFIG_ARCH_TEGRA_241_SOC is enabled.
