  1. cater for moving ocmb out of proc in device tree 

    1) As present ocmb is added under proc chip even though ocmb
is a chip itself.

2) Moved ocmb out of proc chip as it needs to use its own
pib and iic bus

3) cater for moving ocmb out of proc chip in device tree

4) Ensured that ddr4 ocmb targets still use proc pib, fsi bus

Tested:
