ARM: dts: Move omap4 mmio-sram out of l3 interconnect
We need mmio-sram early for omap4_sram_init() for IO barrier init, and
will be moving l3 interconnect to probe with simple-pm-bus that probes
at module_init() time. So let's move mmio-sram out of l3 to prepare for
that.
Otherwise we will get the following after probing the interconnects with
simple-pm-bus:
omap4_sram_init:Unable to get sram pool needed to handle errata I688
