Until now only the BMS system was using the ccadc so there was
no need to create a separate ccadc driver.
However we can run in a configuration with BMS disabled
and clients won't be able to read battery current via ccadc.
Separate the ccadc from the bms, this change in is preparation
to add a ccadc api to read the battery current.

The bms driver calibrates the ccadc channel every few minutes
for offset and gain.
The offset value calibrated needs to be written to the bms hardware
which it uses to adjust all the ccadc readings.
The software has to only adjust for gain for ccadc based readings.
One is not supposed to program the trim offset values in while a
bms conversion in progress. Update the code to try only two times
instead of 10 to check if the conversion is finished, if not enable
the ccadc eoc interrupt and write the values then.

The reset interrupt in the pmic indicates the pmic will shutdown
the msm in few seconds - it does so by lowering the reset_n line
to the msm.
When this interrupt is triggered it is required that no more ssbi
transactions are initiated and the msm should cleanup and prepare
for the impending shutdown. There is no need to lower ps_hold in
this case as the pmic will shutdown the msm regardless.
Also since we don't want any ssbi transactions, force shutdown
nonboot cpus. This will prevent ssbi transactions to the pmic for
lower/raising nonboot cpu's voltages as they enter/exit idle states.

PM8921 PMIC chip. This chip contains many different types of
regulators with a wide range of abilities and voltage ranges.
Eight different regulator types are available on the PM8921. These
are managed via 7 different type values in the driver:
LDO - low drop out regulator (supports both NMOS and PMOS LDOs)
NLDO1200 - 1.2A NMOS LDO (different control structure than other LDOs)
SMPS - switched-mode power supply
FTSMPS - fast transient SMPS
VS - voltage switch
VS300 - 300mA voltage switch (different control structure than
other switches)
NCP - negative charge pump
The driver interfaces with the PMIC using Qualcomm's SSBI bus.
Calls to this bus are abtracted through the pm8xxx_readb/writeb API.
