There are some AC97 codec and board combinations that have been observed
to take a very long time to respond after the cold reset has completed.
In one case, more than 350 ms was required. To allow users to have sound
on those platforms, we'll wait up to 500ms for the codec to become
ready.
As a board may have multiple codecs, with some faster than others to
reset, we add a module parameter to inform the driver which codecs
should be present.

This quirk sould be reverted. It has the following probems:
1) The quirk was intended to "ASUS MV2-MX SE" motherboards only, but the
ID used matches a much broader range, potentially all boards containing a
VIA chipset model in the family of vendor VIA 0x1106 and audio device ID
0x3288, which encompasses VIA-VT82xx, VIA-VT1xx and VIA-VT20xx chipsets.
2) VIA chipsets rely on azx_via_get_position() to handle correctly dma
transfers during capture. Using POS_FIX_LPIB instead of POS_FIX_VIACOMBO
leads to partially corrupted input buffers during capture. The effects
of this bug are not immediately visible, it took strong DSP expertise,
some expensive signal generator and a spectrum analyzer to identify it
and verify correct behaviour using original default.
3) It's almost certain that the quirk did not fix the real problem,
if there was one. Refer to original submission:

VT1708 has no support for unsolicited events per jack-plug, the driver
implements the workq for polling the jack-detection. The mixer element
"Jack Detect" was supposed to control this behavior on/off, but this
doesn't work properly as is now. The workq is always started and the
HP automute is always enabled.
This patch fixes the jack-detect control behavior by triggering / stopping
the work appropriately at the state change. Also the work checks the
internal state to continue scheduling or not.

When the imux entries are rebuilt in alc_rebuild_imux_for_auto_mic(),
the initialization of index field is missing. It may work without it
casually when the original imux was created by the auto-parser, but
it's definitely broken in the case of static configs where no imux was
parsed beforehand. Because of this, the auto-mic switching doesn't
work properly on some model options.
This patch adds the missing initialization of index field.

The PCI SSID 8086:7270 is commonly used for multiple Apple machines,
thus we can't use it as identifier for a unique model. Because of this
conflict, some machines show weird behavior. For example, MacBook Air
shows Front and Surround speakers although only Surround works due to
the wrongly overridden pin-configuration for imac27.
This patch fixes two things:
- Stop the wrong pin-config override of imac27 by removing PCI SSID
entry for avoiding the wrong mappings,
- Add the generic GPIO setup for Apple machines by checking the codec
SSID vendor bits
