ASoC: Updates for v5.1

Lots and lots of new drivers so far, a highlight being the MediaTek
BTCVSD which is a driver for a Bluetooth radio chip - the first such
driver we've had upstream.  Hopefully we will soon also see a baseband
with an upstream driver!

 - Support for only powering up channels that are actively being used.
 - Quite a few improvements to simplify the generic card drivers,
   especially the merge of the SCU cards into the main generic drivers.
 - Lots of fixes for probing on Intel systems, trying to rationalize
   things to look more standard from a framework point of view.
 - New drivers for Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341,
   Google ChromeOS embedded controllers, Ingenic JZ4725B, MediaTek
   BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328, Spreadtrum
   DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM formatters.

Pull further device memory allocation cleanups (but no API change yet).

To detect potential errors, let's add:

a) build-time warnings when the table size isn't aligned with the enum
list
b) run-time warnings when the values are not initialized. This
requires an increase by one of all values to avoid the default 0.

KASAN reports and additional traces point to out-of-bounds accesses to
the dapm_up_seq and dapm_down_seq lookup tables. The indices used are
larger than the array definition.

Fix by adding missing entries for the new widget types in these two
lookup tables, and align them with PGA values.

Also the sequences for the following widgets were not defined. Since
their values defaulted to zero, assign them explicitly

 snd_soc_dapm_input
 snd_soc_dapm_output
 snd_soc_dapm_vmid
 snd_soc_dapm_siggen
 snd_soc_dapm_sink

The creation of card's id proc file can be moved gracefully into
info.c.  Also, the assignment of card->proc_id is superfluous and can
be dropped.  So let's do it.

Basically this is no functional change but code refactoring, but one
potential behavior change is that now it returns properly the error
code from snd_info_card_register(), which is a good thing (tm).
