While the hardware is capable of some limited asynmmetric modes the
driver does not currently support those modes so tell applications
that only symmetric rates are available.

Add support for EXTMUTE in Zoom2 machine driver. This is necessary
to further reduce pop noise problem. Signal EXTMUTE is connected to
signal GPIO 153 in Zoom2 board.

In addition, change ramp delay value to 3 (218/161/109 ms). With
previous ramp delay value, pop noise was louder. With a longer value
the beep tone can be observed.

According to TRM, an external FET controlled by a 1.8V output signal
can be used to reduce the pop-noise heard when the audio amplifier is
switched on. It is suggested that GPIO6 of TWL4030 be used, but any
other gpio can be used instead. This is indicated in machine driver
with the following twl4030_setup_data members:

-hs_extmute. Set to 1 if board has support for EXTMUTE.

-set_hs_extmute. Set to a callback funcion to control an external gpio
line. Set to NULL if MUTE[GPIO6] pin is used.

Codec driver takes care of enabling and disabling this output during
the headset pop attenuation sequence.

Also add a delay to let VMID settle in ramp up sequence.

ALSA SoC drivers should be specify SND_SOC_AC97_BUS instead, not AC97_BUS.
Without SND_SOC_AC97_BUS defined, an AC97 device will not get correctly
registered on the AC97 bus, which prevents thinks like the WM9712
touchscreen driver from getting probed.
