Normally this bit is 1b'1 by reset, but during our development, it used to be
overwritten in u-boot and lead to some clock operation fail in Linux kernel, that is why we ensure it
in clock driver early phase. IMO, it should be OK to not add a fix tag, since it is just
to make sure the setting is correct and NOT depends on the hardware reset value which
could be changed in u-boot.
