pcf8523: Fix wrong initialization of several registers
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.
TEST=booted mc_bdx1 and verified current consumption of RTC
