clk: samsung: fix missing Tesla FSD dependency on Exynos

The Tesla FSD clock controller driver uses shared parts from Exynos
ARM64 clock drivers, so add proper dependency to fix COMPILE_TEST build
errors like:

  /usr/bin/aarch64-linux-gnu-ld: drivers/clk/samsung/clk-fsd.o: in function `fsd_cmu_probe':
  clk-fsd.c:(.init.text+0x9c): undefined reference to `exynos_arm64_register_cmu'
