ASoC: Samsung: Merge neo1937_wm8753 and neo1973_gta02_wm8753 sound board driver

The neo1973(GTA01) and neo1973_gta02(GTA02) have a very similar audio hardware
setup. They both use the same codec with the same routing to the gsm modem and
bluetooth chip. But they do use different AMPs though and there are some minor
differences in the speaker setup.

As a result most of the code of those two drivers is identical.
So from a maintenance point of view it makes sense to merge them into a single
driver. It also reduces the size of kernel images supporting both the GTA01 and
GTA02.

As a side-effect of this merge the GTA01 for example gains support for routing
audio to and from the bluetooth DAI.
