ASoC: Add PCM3008 ALSA SoC driver
The PCM3008 is a 16-bit stereo audio codec. It accepts left-justified format for ADC, and right-justified format for DAC. Independent power-down modes for ADC and DAC are provided, as well as a digital de-emphasis filter (4 modes). [Merged Makefile & Kconfig, changed asm/gpio.h to linux/gpio.h -- broonie] Signed-off-by: Hugo Villeneuve <hugo@hugovil.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
