clk: samsung: exynos850: Implement CMU_AUD domain
CMU_AUD clock domain provides clocks for ABOX IP-core (audio subsystem). According to Exynos850 TRM, CMU_AUD generates Cortex-A32 clock, bus clock and audio clocks for BLK_AUD. This patch adds next clocks: - bus clocks in CMU_TOP needed for CMU_AUD - all internal CMU_AUD clocks - leaf clocks for Cortex-A32, Speedy FM, UAIF0..UAIF6 (Unified Audio Interface), CNT (counter), ABOX IP-core, ASB (Asynchronous Bridge), DAP (Debug Access Port), I2S Codec MCLK, D_TZPC (TrustZone Protection Controller), GPIO, PPMU (Platform Performance Monitoring Unit), SysMMU, SysReg and WDT ABOX clock was marked as CLK_IGNORE_UNUSED, as system hangs on boot otherwise. Once ABOX driver is implemented, maybe it can be handled there instead.
