pinctrl: mpfs-mssio: use correct regmap function to set bank voltage

Browse source

regmap_assign_bits() is not the correct function to use for an RMW
operation, as it maps to regmap_set_bits() or regmap_clear_bits() and
the former will never zero a bit. Use regmap_update_bits() instead,
which will actually set the bank voltages to what have been requested.
