[PATCH 5/6] clk: samsung: exynos850: Add AUD and HSI main gate clocks

[Sam Protsenko]

Add main gate clocks for controlling AUD and HSI CMUs:
  - gout_aud_cmu_aud_pclk
  - gout_hsi_cmu_hsi_pclk

Those clocks were marked as CLK_IGNORE_UNUSED, as system hangs on
boot otherwise.

While at it, add missing PPMU (Performance Profiling Monitor Unit)
clocks for CMU_HSI.
