arm64: dts: st: set RIFSC as an access controller on stm32mp21x platforms

Similarly to stm32mp23x/25x platforms, the RIFSC is a firewall
controller. Declare it as an access controller, keep the "simple-bus"
compatible in case CONFIG_STM32_FIREWALL is not set and update the
child nodes.

arm64: dts: st: Add I/O sync to eth pinctrl in stm32mp25-pinctrl.dtsi

On board stm32mp257f-ev1, the propagation delay between eth1/eth2
and the external PHY requires a compensation to guarantee that no
packet get lost in all the working conditions.

Add I/O synchronization properties in pinctrl on all the RGMII
data pins, activating re-sampling on both edges of the clock.

arm64: dts: st: Add memory-region-names property for stm32mp257f-ev1

In order to set the AMCR register, which configures the
memory-region split between ospi1 and ospi2, we need to
identify the ospi instance.

By using memory-region-names, it allows to identify the
ospi instance this memory-region belongs to.
