mfd: stm32: Enable regmap fast_io for stm32-lptimer
Because stm32-lptimer need to write in registers in interrupt context enable regmap fast_io to use a spin_lock to protect registers access rather than a mutex. Signed-off-by: Benjamin Gaignard <benjamin.gaignard@st.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
