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]
