arm64: dts: rockchip: rk3568: add XPCS and fixed-clock nodes

This commit adds the Synopsys DesignWare XPCS and two fixed-clock nodes for
GMAC reference clocks to the RK3568 device tree. It places the nodes and adds
necessary properties for board-level configuration.

[Severity: Low]
According to standard Device Tree coding style guidelines
(Documentation/devicetree/bindings/dts-coding-style.rst), should nodes
without a 'reg' property be placed at the top of the file (or the top of
the root node) and sorted alphabetically, before any nodes with a 'reg'
property?

These clock-xpcs-gmac0 and clock-xpcs-gmac1 nodes in
arch/arm64/boot/dts/rockchip/rk3568.dtsi lack a 'reg' property but are
placed directly after ethernet-pcs at fda00000 and before syscon at fdc70000.

Could these be moved to the top of the root node alongside other non-reg
nodes like opp-table?
