What did I do to fix this issue:
1- apt purge alsa-utils
2- apt install alsa-utils
Now everything is working as expected. Maybe some misconfigured stuff to
have a (strangely enough) high value for property mixer and other stuff...

Now I did some great steps ahead! ;-)
I can assume there is some misconfigured alsa stuff in my debootstrapped
armhf jessie distro!!!
First step: from Barebox bootloader I tried to move on/off all pins
connected to the SGTL5000 from SoC iMX6. They are moving good, so I can
assume _NO_HARDWARE_ issue.
Second step: burn a ubuntu armhf image (boundary-devices-jessie) to
match up my system-boot (/etc/fstab and /etc/inittab), adding the
/lib/modules/4.12-rc7/ directory and drivers, and add the uImage for
4.12-rc7 on the sdcard.
Third step: burn on the sdcard the Barebox bootloader instead of the
(unrunningble) u-boot for another board (Nitrogen).
Fourth step: turn on my board with this sdcard.
Sound is working. The levels of the capabilities (PCM, MIC, DAC, ...)
are settable and they are working fine.
I can play and I can record. The only thing is the driver can use only
S24_LE as frequeny for recording but afterall everything is working as
expected.
Now the biggest question:
WTF are working alsa or its configuration in a deboostrapped armhf
distribution? Actually this distro was upgraded two times:
1- Wheezy armel
2- Wheezy armel + armhf
3- Wheezy armhf
4- Jessie armhf
5- apt get dist-upgrade...
Something in between was wrong with alsa. Any help or configuration file
to fix this issue???

May I have a simple configuration file for this?

So, are they good?
If your hardware really uses these pins, then yes :-)
Now looking at other boards where our hardware-guy took the inspiration
(i.e. iMX6 Rex from Fedevel) the device-tree is the same as mine.
MX6QDL_PAD_GPIO_0__CCM_CLKO1 0x030b0
0x130b0 or 0x030b0 the only difference is the PAD_CTL_HYS (1 << 16)
Maybe more strong to noise, but basically they are the same.
But I found an issue when playing data from aplay without specifing the
device or specifying one:
# aplay /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate
48000 Hz, Mono
or
# aplay -D hw:0,0 /usr/share/sounds/alsa/Front_Right.wav
Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate
48000 Hz, Mono
aplay: set_params:1233: Sample format non available
Available formats:
- S24_LE
Maybe some ALSA misconfigured????
This distro is a bootstrapped jessie Debian 8, so some configuration
could be missing or not-so-good-configured.
