arm64: dts: broadcom: Assign clock rates in eth node for RPi5

In Raspberry Pi 5 DTS, the Ethernet clock rates must be assigned
as the default clock register values are not valid for the
Ethernet interface to function.
This can be done either in rp1_clocks node or in rp1_eth node.

Define the rates in rp1_eth node, as those clocks are 'leaf' clocks
used specifically by the Ethernet device only.
