regulator: Add snapshot of qpnp-labibb regulator driver 



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.

          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.
