[PATCH v6 5/6] regulator: pfuze100-regulator: provide pm_power_off_prepare handler

On some boards the SoC can use one pin "PMIC_STBY_REQ" to notify th PMIC about state changes. In this case internal state of PMIC must be preconfigured for upcomming state change. It works fine with the current regulator framework, except with the power-off case. This patch is providing an

[PATCH 00/34 v3] PTI support for x32
