By default, on kernel side, all clocks was temporarly

feature for this serial driver.

_ Add gpio compatible and aliases for stm32h743
_ Add FMC sdram node with associated new bindings value to

_ Add missing HSI and CSI oscillators nodes needed

Clock sources could be:
_ HSE (High Speed External)
_ HSI (High Speed Internal)
_ CSI (Low Power Internal)
These clocks can be used as clocksource in some configuration.
By default, HSE is selected as clock source.
_ Set HSE to 25Mhz for stm32h743i-disco and eval board
By default, the external oscillator frequency is defined at
25 Mhz in SoC stm32h743.dtsi file.
It has been set at 125 Mhz in kernel DT temporarly waiting for
