ARM: multi_v7_defconfig: Enable Trats2 audio codec, touchscreen and sensors

The Exynos4412-based Trats2 board has CM36651 proximity/ambient light
sensor, MMS114 touchscreen and Wolfson Microelectronics WM1811 CODEC.
Enable them in defconfig to get some testing coverage and use its
features.

While saving defconfig the SND_SOC_ODROIDX2 is removed because it does
not exist since commit ee12a817 ("ASoC: samsung: Remove unused
Odroid x2/u3 machine driver").
