mtd: rawnand: stm32_fmc2: use FMC2_TIMEOUT_5S for timeouts
FMC2_TIMEOUT_5S will be used each time that we need to wait. It was seen, during stress tests in an overloaded system, that we could be close to 1 second, even if we never met this value. To be safe, FMC2_TIMEOUT_MS is set to 5 seconds. Signed-off-by: Christophe Kerello <christophe.kerello@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
