The base address of I2S 0 controller is similar in exynos4 and exynos5
platforms. So this patch defines a common macro for the I2S controller
0 base address in both the platforms and use the same macro.

This patch also defines the I2S controller 1,2 base addresses in exynos5
and correct the I2S controller 1 base address in exynos4

As per the TRM, these addresses (I2S1 and I2S2) are 0x13960000 and
0x13970000 respectively on Exynos4412 SoC.
Please verify.
I didn't verify Exynos4412 before. I will send a new patch for this.
