When the system is suspended while a PCM is paused, it doesn't receive
the SUSPEND trigger. So, the SOF driver has to ensure that the PCM and
the widgets associated with the paused PCM are freed in the firmware
during suspend. This is handled in the
sof_tear_down_left_over_pipelines() call. But since the state of this
PCM is SUSPENDED, we end up clearing the prepared flag for the PCM
before freeing it. This results in IPC errors while freeing the widgets.
But because the widget use_counts are reset to 0 even though the IPC
fails, releasing the paused stream after resuming from suspend proceeds
normally.
Fix the IPC errors by removing the clearing of the prepared flag in
sof_set_hw_params_upon_resume(). In fact, we can remove the
sof_set_hw_params_upon_resume() and call
snd_sof_dsp_hw_params_upon_resume() directly. This will ensure that the
PCM is freed in the firmware before the IPC's for freeing the widgets
are sent.

As pointed out by Sascha Hauer, this patch changes:
if (pmc->config && !pcm->config->prepare_slave_config)
<do nothing>
to:
if (pmc->config && !pcm->config->prepare_slave_config)
snd_dmaengine_pcm_prepare_slave_config()
This breaks the drivers that do not need a call to
dmaengine_slave_config(). Drivers that still need to call
snd_dmaengine_pcm_prepare_slave_config(), but have a NULL
pcm->config->prepare_slave_config should use
snd_dmaengine_pcm_prepare_slave_config() as their prepare_slave_config
callback.

The max98090 driver has a custom put function for some controls which can
only be updated in certain circumstances which makes no effort to validate
that input is suitable for the control, allowing out of spec values to be
written to the hardware and presented to userspace. Fix this by returning
an error when invalid values are written.

ALSA fireworks driver has a bug in its initial state to return count
shorter than expected by 4 bytes to userspace applications when handling
response frame for Echo Audio Fireworks transaction. It's due to missing
addition of the size for the type of event in ALSA firewire stack.

Pointer substream is being dereferenced on the assignment of pointer card
before substream is being null checked with the macro PCM_RUNTIME_CHECK.
Although PCM_RUNTIME_CHECK calls BUG_ON, it still is useful to perform the
the pointer check before card is assigned.

The third argument of usb_maxpacket(): in_out has been deprecated
because it could be derived from the second argument (e.g. using
usb_pipeout(pipe)).
N.B. function usb_maxpacket() was made variadic to accommodate the
transition from the old prototype with three arguments to the new one
with only two arguments (so that no renaming is needed). The variadic
argument is to be removed once all users of usb_maxpacket() get
migrated.

in case it gets -EPROBE_DEFER, thus it will be indicated many times.

For making easier to test, add the new quirk_flags bits 17 and 18 to
enable and disable the generic implicit feedback mode. The bit 17 is
equivalent with implicit_fb=1 option, applying the generic implicit
feedback sync mode. OTOH, the bit 18 disables the implicit fb mode
forcibly.
