dt-bindings: phy: mediatek,tphy: allow simple nodename pattern

The pattern for the nodename only allows t-phy@... , however, for the case
when the t-phy has no `reg` and only `ranges` (basically when the t-phy
is just a parent node), dtc will throw this warning:

Warning (unit_address_vs_reg): /t-phy@1a243000: node has a unit name, but no reg or ranges property

For a node like this:

	sata_phy: t-phy@1a243000 {
		ranges;

		sata_port: sata-phy@1a243000 {
			reg = <0 0x1a243000 0 0x0100>;
		};
	};

it is normal that the parent node 't-phy' would be without any address, as in:

	sata_phy: t-phy {
		ranges;

		sata_port: sata-phy@1a243000 {
			reg = <0 0x1a243000 0 0x0100>;
		};
	};

because being just a holder it does not have its own reg.

However the binding does not allow such a name for the t-phy, so with this
patch, making the `@[0-9a-f]+` part optional, such node is possible.
