ASoC: Standardize ASoC menu

ASoC: Standardize ASoC menu

Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Current Kconfig menu at [ALSA for SoC audio support] has no rules.
So, some venders are using menu style, some venders are listed each drivers
on top page, etc. It is difficult to find target vender and/or drivers
because it is very random.

Let's standardize ASoC menu, like below

	--- ALSA for SoC audio support
	      Analog Devices  --->
	      AMD  --->
	      Apple  --->
	      Atmel  --->
	      Au1x  ----
	      Broadcom  --->
	      Cirrus Logic  --->
	      DesignWare  --->
	      Freescale  --->
	      Google  --->
	      Hisilicon  --->
	      ...

One concern is *vender folder* alphabetical order vs *vender name*
alphabetical order were different. For example "sunxi" menu is
"Allwinner".
