[PATCH] arm64: dts: ti: k3-am642-phyboard-electra: Fix PRU-ICSSG Ethernet ports

[Wadim Egorov]

For the ICSSG PHYs to operate correctly, a 25 MHz reference clock must
be supplied on CLKOUT0. Previously, our bootloader configured this
clock, which is why the PRU Ethernet ports appeared to work, but the
change never made it into the device tree.

Add clock properties to make EXT_REFCLK1.CLKOUT0 output a 25MHz clock.
