[net-next v11 2/7] ARM: dts: nxp: mxs: Adjust the imx28.dtsi L2 switch description

The current range of 'reg' property is too small to allow full control
of the L2 switch on imx287.

As this IP block also uses ENET-MAC blocks for its operation, the address
range for it must be included as well.

Moreover, some SoC common properties (like compatible, clocks, interrupts
numbers) have been moved to this node.
