thermal/drivers/tegra: Correct compile-testing of drivers

All Tegra thermal drivers support compile-testing, but the drivers are
not available for compile-testing because the whole Kconfig meny entry
depends on ARCH_TEGRA, missing the alternative COMPILE_TEST dependency
option. Correct the Kconfig entry.
