Doing what is explained in this post make it to work but spidev isn't anymore controlled through /boot/armbianEnv.conf file but the DT.
 
I used the "quick and dirty" fix for now by using "rohm,dh2228fv" which is already in the spidev_dt_ids[] list and avoid me creating a new build with a patch to modify drivers/spi/spidev.c
 
So basically, I used armian-config to edit the Device Tree (System => Dtc),
Browse the DT over soc => spi@1c68000
And I added these lines :
spi@1c68000 { ... spidev@0x00 { compatible = "rohm,dh2228fv"; spi-max-frequency = <100000000>; reg = <0x00>; }; }  
And the same for the second SPI controller :
 
spi@1c69000 { ... spidev@0x00 { compatible = "rohm,dh2228fv"; spi-max-frequency = <100000000>; reg = <0x00>; }; }  
I also had to remove the spidev stuff from /boot/armbianEnv.conf (No spi-spidev overlay)

This way, I get two SPI devices and the SBC is working again with 5.15 kernel :
 
# ls /dev/ | grep spi spidev0.0 spidev1.0
