Haven't read enough of the coreboot source code to be able to say if and
where those bits are written by coreboot.
They are in the LDN A of the SIO chip, bits 5 and 6 in CR E4h. See the
SIO datasheet.
Since VRTC is the power well for that unit of the chip, removing the
power and the BIOS battery for a minute should reset those bits to 0.
