regulator: Add snapshot of qpnp-labibb regulator driver

Browse source 
Add snapshot of QPNP LABIBB regulator driver that supports controlling
the display bias voltage rails on QTI PMICs that powers up LCD or
AMOLED panels.

This snapshot is taken as of msm-4.14
commit 9bb584ae3a9d ("msm/sde/rotator: Add rev checks for sdmmagpie").

This change also splits some functions to fix cyclomatic complexity
warnings.

help
This driver supports voltage regulators in Qualcomm Technologies, Inc.
PMIC chips which comply with QPNP LAB/IBB regulators. QPNP LAB and IBB
are SPMI based PMIC implementations. LAB regulator can be used as a
regular positive boost regulator. IBB can be used as a regular
negative boost regulator. LAB/IBB regulators can also be used
together for LCD or AMOLED on QTI PMICs like PMI8998.
