MIPS: Octeon: Add DTS for D-Link DSR-1000N

Add DTS for D-Link DSR-1000N that is usable as is without any "pruning"
with APPENDED_DTB. Split out the common parts from octeon_3xxx.dts
into octeon_3xxx.dtsi.

Compared to builtin generic DTB, we can specificy fixed links properly
and avoid probing non-existent I2C devices.
