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

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.

Maybe Sangsu Park?

Is there any reason to use the offset, 0x02910000?

[...]

And I think, this patch should be patch-set with your '[PATCH] ARM: EXYNOS:

Thanks.

Okay. In the next version I will send it along with clock support for audio.
