we only add the property of regulator and clock to cpu0 and cpu4 node,
but if cpu4~cpu7 is down and then we up cpu5~cpu7, they will can not
get their regulator and clock. So we should add the properties to all
cpu node.

The gc2145 always rewrite init setting,
when change state from preview to capture.
That will get exposure time again when capture picture,
it causes capture exposure time different with preview.
To fix this issue, following changes introduced:
- reconfig gc2145 reg_table.
- add gc2145_aec_ctrl function calculate Capture shutter.

Now a regulator device can supply multiple consumers at the same time,
if a consumer starts and set a low voltage, another consumer doesn't
start in kernel but has been set a high frequency in bootloader will
abort.
This patch Adds support to limit min_uV during kernel startup to make
sure the voltage can suit the needs of all consumers.

The power_allocator thermal governor should get utilization of cooling
device to calculate dynamic power, but the powersave, userspace and performance
devfreq governor don't updade stats, so the utilization is inaccurate.
This patch adds support to update status when get requested power, so that
power_allocator can also work properly when use powersave, userspace and
