[PATCH 4/6] ARM: dts: samsung: exynos4212-tab3: Add MCLK2 clock to WM1811 codec config

In the schematics, the MCLK2 pin is shown as connected to CODEC_CLK32K,
which is derived from the same 32KHZ_PMIC clock as Bluetooth/WiFi and
GPS clocks. 32KHZ_PMIC is connected to the BTCLK pin, represented in
mainline as S2MPS11_CLK_BT.

Add the MCLK2 clock to the WM1811 codec clock property to properly
describe the hardware.
