It is currently possible to have CONFIG_SND_ATMEL_SOC_SSC=y with either
CONFIG_SND_ATMEL_SOC_PDC=m or CONFIG_SND_ATMEL_SOC_DMA=m. This results in a
driver that compiles but does not link with this kind of error:
sound/built-in.o: In function `atmel_ssc_set_audio':
(.text+0x87d90): undefined reference to `atmel_pcm_pdc_platform_register'
sound/built-in.o: In function `atmel_ssc_put_audio':
(.text+0x8879a): undefined reference to `atmel_pcm_pdc_platform_unregister'
Introduce new config options SND_ATMEL_SOC_SSC_PDC and
SND_ATMEL_SOC_SSC_DMA which should be used by the board drivers and the
correct logic to properly select the SND_ATMEL_SOC_PDC and
SND_ATMEL_SOC_DMA states.

The SND_AT91_SOC_SAM9G20_WM8731 and SND_AT91_SOC_SAM9X5_WM8731 machine
driver symbols select SND_SOC_WM8731 which depends on SND_SOC_I2C_AND_SPI.
So the machine driver symbols need to depend on SND_SOC_I2C_AND_SPI as well,
otherwise we might end up with a invalid configuration, which will sooner or
later upset the randconfig auto-builders.

This AT91 specific Kconfig option removed the code that dealt with
programmable clocks. Each AT91 SoC embeds programmable clocks and
there is little gain to remove this code in case that such a clock
is not used.
If this option is not selected, it causes certain drivers to fail
to build. We simply remove this option instead of adding code just
to build a workaround.

commit 739be96 "ASoC: Fix build dependency for SND_ATMEL_SOC_SSC"
introduces below build warnings:
drivers/misc/Kconfig:212:error: recursive dependency detected!
drivers/misc/Kconfig:212: symbol ATMEL_SSC is selected by SND_ATMEL_SOC_SSC
sound/soc/atmel/Kconfig:9: symbol SND_ATMEL_SOC_SSC is selected by SND_AT91_SOC_SAM9G20_WM8731
sound/soc/atmel/Kconfig:18: symbol SND_AT91_SOC_SAM9G20_WM8731 depends on ATMEL_SSC
SND_ATMEL_SOC_SSC needs ATMEL_SSC to pass compilation.
This patch remove the "select ATMEL_SSC" from SND_ATMEL_SOC_SSC to avoid above
warnings. And then ensures all the machine drivers that select SND_ATMEL_SOC_SSC
need to depend on ATMEL_SSC.
