Device state is updated incorrectly during codec probe when
the wsa881x soundwire slave device is in suspend state, resulting
in register read/write failures. Update the device state during
device probe instead of codec probe.

On msmcobalt reference platform, earpiece path is not connected
to receiver, instead speaker path is used as receiver. So handset
AANC(Adaptive Active Noise cancellation) needs to be supported
on speaker path. Change enables ANC support on speaker path.

Dynamic detection between wcd9335 and wcd934x codecs is supported on
msmcobalt. Probe sequence of the two codec drivers can occur in any
order. MCLK initialization is common for the two codecs which gets
called twice. Avoid wcd934x codec's probe sequence from resetting
wcd9335 codec's native mclk pinctrl if the pinctrl is already
initialized.

Explicitly send device disconnect notification to client
so that client can disable audio streams. This will in turn
enable sound usb driver to release usb device and notify device
removal to user-space. User-space will clean up audio session.
Without this change sound usb driver is blocking usb device
release till audio streams are disabled. However, audio streams
are only disabled when user-space cleans up audio session on usb
device removal which is blocked. This change is trying to fix
this deadlock condition by notifying device disconnect to clients
explicitly.
