ASoC: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

ASoC: adau1701: Update to use maple tree register cache

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.

Update the adau1701 driver to use the more modern data structure.

ASoC: sigmadsp: Restructure in preparation for fw v2 support

The v2 file format of the SigmaDSP takes a more declarative style compared
to the imperative style of the v1 format. In addition some features that are
supported with v2 require the driver to keep state around for the firmware.
This requires a bit of restructuring of both the firmware loader itself and
the drivers making use of the firmware loader.

Instead of loading and executing the firmware in place when the DSP is
configured the firmware is now loaded at driver probe time. This is required
since the new firmware format will in addition to the firmware data itself
contain meta information describing the firmware and its requirements and
capabilities. Those will for example be used to restrict the supported
samplerates advertised by the driver to userspace to the list of samplerates
supported for the firmware.

This only does the restructuring required by the v2 format, but does not
yet add support for the new format itself.

ASoC: adau1701: allow configuration of PLL mode pins

The ADAU1701 has 2 hardware pins to configure the PLL mode in accordance
to the MCLK-to-LRCLK ratio. These pins have to be stable before the chip
is released from reset, and a full reset cycle, including a new firmware
download is needed whenever they change.

This patch adds GPIO properties to the DT bindings of the Codec, and
implements makes the set_sysclk memorize the configured sysclk.

Because the run-time parameters are unknown at probe time, the first
firmware download is postponed to the first hw_params call, when the
driver can determine the mclk/lrclk divider. Subsequent downloads
are only issued when the divider configuration changes.
