Are you sure ? According to the PCF50633 manual,

- the behaviour when setting BVMCTL.bvmlvl = 0 is unspecified [1],
  and
- Vbat is only considered if OOCCTL.usbbatchk = 1 [2], which is
  neither the NoPower default nor what u-boot sets [3]. The kernel
  doesn't touch OOCCTL either.

[1] 8.5.5, table 37
[2] 8.5.6, second to last paragraph, and also 8.1.5, table 13
[3]
