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

This commit adds the XPCS device node, its pcs-mii sub-nodes, and two
fixed-clock reference nodes to the RK3568 SoC device tree. The XPCS node is
disabled by default and intentionally omits the phys and phy-names
properties in the dtsi.

[Severity: Low]
Is this assumption about dtbs_check accurate? dt-validate enforces
unconditional required property lists against all nodes matching the
compatible string, regardless of their status.

[Severity: Low]
Will this omission result in missing-property validation warnings during
make dtbs_check for any board including rk3568.dtsi? 

Because the rockchip,rk3568-xpcs schema unconditionally requires phys and
phy-names, dtbs_check will likely flag this disabled node for lacking them
when validating the compiled dtb.
