snd-soc-sst-bytcr-rt5640 will be loaded automatically if you use snd-intel-sst-acpi instead of snd-soc-sst-acpi, you can blacklist the latter using a file in /etc/modprobe.d (look up the details), or just remove snd-soc-sst-acpi.ko from the installation dir as a dirty hack.
Indeed. I always loaded snd-soc-sst-acpi before snd-intel-sst-acpi, so I could not observe it gives a different result.
In my tests I used the code from mainline linux.
Ok. That is what I am doing too.
Note that different drivers expect different firmwares, you cannot mix them:
snd-soc-sst-acpi -> fw_sst_0f28.bin-48kHz_i2s_master snd-intel-sst-acpi -> fw_sst_0f28.bin snd-intel-sst-acpi -> fw_sst_0f28_ssp0.bin (renamed to fw_sst_0f28.bin)
Ok. I re-ran the tests like that.
After loading snd-intel-sst-acpi, the kernel says:

The sound card appears, but then if I try to play something:

[ 95.164749] Baytrail Audio Port: ASoC: no backend DAIs enabled for Baytrail Audio Port
This is dpcm enabled driver
So please route the FE to BE and it should work...
Vinod
The messages are exactly the same with both firmwares (fw_sst_0f28.bin and fw_sst_0f28_ssp0.bin).
Maybe I forgot to load another module?
Side note: snd-intel-sst-acpi and snd-soc-rt5640 both have usage count 1 without dependent modules, that requires a reboot between each test.
Thanks for your help, it helped me make progress even if it still is not success.

Nicolas, this can be done by using the commands from here: http://mailman.alsa-project.org/pipermail/alsa-devel/2015-June/094080.html
In particular: amixer -c0 sset 'codec_out0 mix 0 pcm0_in' on amixer -c0 sset 'media0_out mix 0 media1_in' on
Ciao, Antonio
P.S. Vinod, please check your email client, it looks like sometimes there is no In-Reply-To header in messages from you and the threading of messages gets broken.

Thanks for the explanations, that saved me a lot of time.
It changed the result a bit. Now, aplay fails, but it takes one or two seconds before starting ("Playing raw data...") and again one or two seconds before failing ("Unable to install hw params:..."). In the meantime, the kernel printed this:

I have attached the full output of amixer in case it is useful. I am shooting in the dark here. Is there a documentation to understand what all these settings do?
