[PATCH v2 06/12] mtd: rawnand: stm32_fmc2: use FMC2_TIMEOUT_MS for timeouts

[Christophe Kerello <christophe.kerello@st.com>]

This patch removes the constant FMC2_TIMEOUT_US.
FMC2_TIMEOUT_MS is set to 5 seconds and this constant is used
each time that we need to wait (except when the timeout value
is set by the framework)
