QPNP Flash v2 LED driver supports the flash LED peripheral on
QTI PMICs like PMI8998, PM8150L and their derivatives to support
camera flash operation.
This is taken as a snapshot from msm-4.14 kernel
'commit 9bb584ae3a9d ("msm/sde/rotator: Add rev checks for sdmmagpie")'
This change also splits some functions to fix cyclomatic complexity
warnings.
