[PATCH v2 3/3] ARM: dts: exynos: Add sound support to Midas

[Sylwester Nawrocki <s.nawrocki@samsung.com>]

From: Simon Shields <simon@lineageos.org>

Update the never-mainlined "samsung,trats2-audio" binding and instead
use the new "samsung,midas-audio" binding.

Signed-off-by: Simon Shields <simon@lineageos.org>
[s.nawrocki: fixed DAPM routing entries for MICBIAS1/2, adjusted to
 new cpu/codec binding, corrected the regulator nodes indexing]
Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>

Changes for v2:
 - reordering to maintain alphabetical order,
 - corrected the fixed voltage regulator nodes indexing,
 - whitespace fixes.
