ARM: dts: mvebu: Add CRS305-1G-4S board 



MikroTik CRS305-1G-4S board has a switch chip with an integrated
Marvell Prestera 98DX3236 CPU.

This commit includes two board variants, namely the factory
default one and a Bit variant. The Bit variant has a
bigger Macronix flash.

This device tree includes basic Linux support.
