For power off, downstream only clears bit 8 and leaves all other bits
untouched, whereas this here ends up setting bit 8 and clearing all
others, due to how sysconf-poweroff parses the DT.
I noticed this discrepancy while debugging some reboot related
differences between up- and downstream and it's useful to align the
behaviour here.
Note: for reboot downstream seems to be incorrectly writing 0x00000002
and not just setting bit 1 (which is the only R/W bit in this
register), so we keep that one as-is here.
