For Chrome OS the normal MRC cache should be cleared when a hardware
retrain recovery request is observed. The reason is that since there
are 2 different MRC cache slots there needs to be a mechanism which
allows an end user make a system bootable again if the MRC settings
happen to not allow the system to boot any longer. Therefore, one
just needs to enter recovery with the hardware retrain flag and
the system normal MRC cache slot will be invalidated.

In the case where the RTC is initialized after the battery is
completely drained the bits for power_mode and cof_selection are set up
with wrongly applied masks.
In the case where the RTC is re-initialized again with no power-loss
after the last initialization the bits for cap_sel, power_mode and
cof_selection are not shifted to the right position.
Both errors lead to a wrong initialization of the RTC and in turn to a
way larger current consumption (instead of 120 nA the RTC current rises
to over 2 µA).
This patch fixes both errors and the current consumption is in the right
range again.
