Add a snapshot of several Qualcomm Technologies, Inc. QPNP PMIC
peripheral drivers that are used for User interface modules like
display panels (LCD, AMOLED) and flash LED. Fixed some checkpatch
warnings reported with error logs containing function names which
are not needed.
This snapshot is taken as of msm-4.9 commit
1c7b30fefbb5 ("Merge "Revert "soc: qcom: pil: Log the TZ NMI
caused subsystem err fatal""").
