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'

Fixes: e3f3dc3810d3 ("clk: samsung: fsd: Add cmu_peric block clock information")

What I forgot to mention - the commit being fixes is in my tree, so this
should go as well via Samsung SoC.
