Initial snapshot of vm-bms device driver is taken from msm-3.18
kernel version @ commit f8b6819d0432d6 ("msm: ipa: Fix to
handle NULL pointer dereference")
Add vm-bms, batterydata-interface, battery-lib support
Change spmi driver framework to platform driver framework in 4.9
kernel. Add support to access spmi register via regmap.
