ARM: OMAP2+: Fix module address for modules using mpu_rt_idx

Browse source

If we use device tree data for a module interconnect target we want
to map the control registers from the module start. Legacy hwmod platform
data however is using child IP offsets for cpsw module with mpu_rt_idx.

In cases where we have the interconnect target module already using device
tree data with legacy hwmod platform data still around, the sysc register
area is not adjusted for mpu_rt_idx causing wrong registers being accessed.

Let's fix the issue for mixed dts and platform data mode by ioremapping
the module registers using child IP offset if mpu_rt_idx is set. For
device tree only data there's no reason to use mpu_rt_idx.

"ti,hwmods" support")
