[PATCH 1/5] arm64: dts: st: Add st,io-sync into eth2_rgmii_pins_b

Add st,io-sync into eth2_rgmii_pins_b to configure the RGMII data pins
for DDR operation. This pinmux is used on DH electronics STM32MP23xx
and STM32MP25xx DHCOS DHSBC.

Fixes: e2fce4620933 ("arm64: dts: st: Add pinmux nodes for DH electronics STM32MP23xx/STM32MP25xx DHCOS SoM and Breakout Board")
