[PATCH 1/2] ARM: dts: stm32: Synchronize DHCOR DTs with Linux 5.15.12

[Marek Vasut <marex@denx.de>]

Synchronize DH DHCOR DTs with Linux commit 25960cafa06e ("Linux 5.15.12").
There is no functional change to the resulting DTs. The eeprom0 alias is
now reinstated in SoM u-boot dtsi, the PHY reset GPIO is reinstated in AV96
u-boot dtsi.
