snd_gf1_pcm_new() and snd_gf1_rawmidi_new() take a pointer to a pointer of a
PCM/MIDI where if this parameter is provided the newly allocated object is
stored. All callers pass NULL though, so remove the parameter. This makes
the code a bit cleaner and shorter.

snd_es1688_pcm() takes a pointer to a pointer of a PCM where if this
parameter is provided the newly allocated PCM is stored. This PCM is also
available from the pcm field of the snd_es1688 struct that got passed to the
same function. This patch updates all callers which passed a pointer to use
that field instead and then removes the parameter from the function. This
makes the code a bit shorter and cleaner.

__fls has the same semantics as ld2, so there is no need to re-implement it.
Furthermore a lot of architectures have custom implementations of __fls that
are able to use special hardware instructions to compute the result. This
makes the code slightly shorter and faster.

Instead of opencoding them use the standard roundup_pow_of_two() and
rounddown_pow_of_two() helper functions. This gets rids one of the few users
of the custom ld2() function and also makes it a bit more obvious what the
code does.

The difference between __ffs and ffs is that ffs will return a one based
index whereas __ffs will return a zero based index. Furthermore ffs will
check if the passed value is zero and return zero in that case, whereas
__ffs behavior is undefined if the passed parameter is 0.
Since we already check if the mask is 0 before calling ffs and also subtract
1 from the result __ffs is the better choice.

ASoC: Fixes for v3.19
A few fixes for v3.19, a few driver specifics and one core fix which

Use the new wildcard msbits constraints instead of installing a constraint

Currently the msbits constraints requires to specify a specific sample
format width for which the constraint should be applied. But often the
number of most significant bits is not sample format specific, but rather a
absolute limit. E.g. the PCM interface might accept 32-bit and 24-bit
samples, but the DAC has a 16-bit resolution and throws away the LSBs. In
this case for both 32-bit and 24-bit format msbits should be set to 16. This
patch extends snd_pcm_hw_constraint_msbits() so that a wildcard constraint
can be setup that is applied for all formats with a sample width larger than
the specified msbits. Choosing the wildcard constraint is done by setting
the sample width parameter of the function to 0.

If the sound card is made up of discrete components, each with their own
driver (e.g. like in the ASoC case), we might end up with multiple msbits
constraint rules installed. Currently this will result in msbits being set
to whatever the last rule set it to.
This patch updates the behavior of the rule to choose the minimum (other
than zero) of all the installed rules.

Set the CODEC driver's suspend_bias_off flag rather than manually going to
SND_SOC_BIAS_OFF in suspend and SND_SOC_BIAS_STANDBY in resume. This makes
the code a bit shorter and cleaner.
Since the ASoC core now takes care of setting the bias level to
SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually
anymore either.
The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe()
can also be removed as the core will automatically do this after the CODEC
has been probed.

Commit 04489eeb02a4 ("ALSA: wm8750: add missing VREF output") added the
previously missing VREF widget. And while adding the widget as OUTPUT widget
silences the error of the missing widget it should have rather been a VMID
widget.
The VREF widget is only used internally as a source for the VREF input of
the Out3 Mux. Selecting that input means that the path should be kept
powered up at the VREF/VMID voltage, but that there is no actual audio
signal. Using a VMID widget will do this, whereas using a OUTPUT widget will
simply cause the path to completely power down.

System clock is necessary for rt5670 JD function. We assume system
clock source will be set in machine driver. So there are two things
left we should do in codec driver.
1. Set sysclk to codec internal clock in probe since machine driver
may not do that before JD function is registered.
2. Power up PLL once sysclk source is switched to PLL.
