ASoC: usb: move the switch setting to more appropriate location

There is a delay between creation of sound card and creating of
corresponding steam. Currently we set the switch at the time of
creation of card. And later streams get created, so its more
optimal if we set the switch only after creating the stream.

ASoC: wcd9310: Fix DMIC current leakage after disable

Observed after disabling DMIC path, some DMICs observe
power leakage of around 2mA and affecting power numbers.
This happens due to the DMIC clock runs off MCLK. 2 Stage
of Dividers are used to  generate various DMIC Clock Freq.
Since the SW Enable/Disabling is async to MCLK, the divider
will either hold the last stage 0 or 1.
Manually force the digital mic clock pin to GPIO mode from
functional mode through the TLMM mux option and force the value
of DMIC voltage to 0V. This will avoid any current leakage.

ALSA: core: Fix crash by avoiding appl_ptr crossing 32-bit boundary

Incase of A2DP usecase using proxy driver, appl_ptr has
boundary value as 0x60000000 frames in sw_params for stereo(2 channels).
When this value crosses 0x40000000, then userspace calculating
appl_ptr at bytes results in crossing 32-bit value 0x100000000,
and points to 0x0 offset which can result in crash or pop.
To avoid above scenario, set the sw_params appl_ptr boundary value
within 0x40000000. Added proper check at sw_params update
to set this value correctly within 32-bit boundary(frames).
