imx93-var-som: ahab: U-boot is hanging

[Mathieu Othacehe]

Hello,

I performed a bisection and was able to fix that issue by reverting
three commits on v2024.04-rc1:

0585c28fda1007e4a90dea5f70723cff0b63dd98
eed8294b75a5908a486945ff6655d4dc9aae5fed
ee23d7466c77d01ee63efb76db2c5fd3b7cdd6f7

It is still unclear to me how those FEAT_HAFDBS related commits can be
linked to my issue. 

Possibly my issue is a race condition and the timing shifts introduced
by those three commits are enough to make the issue go away.

To be continued...

Thanks,

Mathieu
