After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

Constifying "struct snd_soc_ops" moves some data to a read-only section, so
increase overall security.
This structure is also part of scripts/const_structs.checkpatch.
As an example, on a x86_64, with allmodconfig:
Before:
text data bss dec hex filename
6315 3696 0 10011 271b sound/soc/intel/boards/ehl_rt5660.o
After:
text data bss dec hex filename
6379 3648 0 10027 272b sound/soc/intel/boards/ehl_rt5660.o

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Add a new machine driver to interface with WM8804. The code is based
on settings found in sound/soc/bcm/hifiberry-digi.c in the Raspberry
PI tree.
Tested on Up2 with Digi+ IO (capture+playback) and Digi+ PRO (playback
with two local oscillators supported). The codec is clock master in
both cases.
Capture support has known clocking restrictions: the transmitter needs
to be active for the clock recovery, the "Tx Source" mixer set to
"S/PDIF RX". Playback will only work while capture is active.
When Capture is not desired, or when there is no RX connector, the "Tx
Source" mixer should be set to "AIF"
