[PATCH v2 18/25] mfd: axp20x: add V_OFF to writeable regs for AXP20X and AXP22X

The V_OFF register has its first 3 read-write bits for the minimal voltage (Voff) of the battery before the system is automatically shut down due to the power being too low. This adds V_OFF register to the writeable registers of AXP20X and AXP22X PMICs. Signed-off-by: Quentin Schulz
