power: pmic: tps65218: Fix tps65218_voltage_update function
Currently while setting the vsel value for dcdc1 and dcdc2
the driver is wrongly masking the entire 8 bits in the process
clearing PFM (bit7) field as well. Hence describe an appropriate
mask for vsel field and modify only those bits in the vsel
mask.
