I'm pretty sure that's how the old TI PM branch was initializing them to
disable voltctrl I2C use on init. But if these are not the issue I guess
no need to mess with them.

Could it be that we have wrong voltage tables for 4460 in the mainline
kernel? See earlier commit 32236a84906f ("ARM: OMAP2+: Update 4430
voltage controller operating points").
