last days I've been trying to isolate the hung cause of a customer board, and also SabreSD board, when using the Freescale's Linux fork of 3.10.9 with 2013.10 U-Boot.

Do I understand correctly that this happens only with the FSL kernel, i. e. not with mainline Linux?

Exactly.

What exactly is the effect of calling your set_anatop_bypass() function? Why would that be needed on the FSL kernel, and not on mainline?

Mainline seems to not drive the pmic while the FSL kernel does. So it seems we ought to bypass the internal LDO.
