This patch adds all the required clock instances for audio
subsystem and adds the clock alias names for sclk-i2s and
i2s-bus clks. This patch also do the static mapping
of audss clock base address to control audss clocks in CMU
clock framework.

Changes since V2:
- Rebased on 3.7-rc3
Changes since V1:
- Rebased on 3.6-rc6
- Modified some of the clk names as suggested by Kukjin Kim
- Added NULL in place of cdclk of sclk_audio0 src list as it
is machine dependent and I am not using it as src.
