SMPS10 has two outputs OUT1 and OUT2 and have one input IN1.
SMPS10-OUT2 is connected to SMPS10-IN1 and can be configured either
in BOOST mode or BYPASS mode. regulator_enable of SMPS10-OUT2 configures
it in BOOST mode. For BYPASS mode regulator_allow_bypass() API can be
used. SMPS10-OUT1 is connected to SMPS10-OUT2 and can be enabled using
regulator_enable().

This sequence can create regulator to be never register.
In probe, we register regulator from 0 to max_id.
Here smps10-out1 comes first and see the supply as smps10-out2 which is
not registered yet and so will fail with PROBE_DEFER
When again it tries, the same issue.
I think we need to reverse the sequence, SMPS10-OUT2 and then SMPS10-OUT1.
