BPI M1 hangs at mounting root filesystem from SATA disk since r345948

[Peter Jeremy]

(To be precise, the BPi powers itself down, it doesn't hang).

It doesn't make any sense to me either but I get exactly the same problem
booting FreeBSD-12.1-RELEASE-arm-armv7-BANANAPI.img.xz (r354233) on a
BPi-M1.  hw.regulator.disable_unused=0 makes it work and I'm currently
building a new world (which will take some time).
