[PATCH] ARM: EXYNOS: Add static mapping for EXYNOS Audio Subsystem

[Padmavathi Venna]

The CMU of EXYNOS can't control Audio Subsystem's clocks because
AUDSS SFRs aren't located in CMU. But AUDSS is a kind of CMU for
Audio Subsystem and need to use clock framework. This mapping
address will be used for AUDSS clock control.
