ARM: zynq: Fix OCM mmio-sram node

First of all addresses where addresses for OCM controller not for OCM memory itself. Also move OCM node from zc702 to generic dtsi to be avalable for everybody. Also remove ocm-sram node which can't be used with zynq pm.c which expects only flat structure. Right now OCM is used for saving suspend code.
