MIPS: mscc: ocelot: add MIIM1 bus

Browse Source 
There is an additional MIIM (MDIO) bus in this SoC so let's declare it
in the dtsi.

This bus requires GPIO 14 and 15 pins that need to be muxed. There is no
support for internal PHY reset on this bus on the contrary of MIIM0 so
there is only one register address space and not two.
