bus: ti-sysc: Fix module register ioremap for larger offsets

/**

 * syc_ioremap - ioremap register space for the interconnect target module

 * @ddata: deviec driver data

 * @ddata: device driver data

 *

 * Note that the interconnect target module registers can be anywhere

 * within the first child device address space. For example, SGX has

 * them at offset 0x1fc00 in the 32MB module address space. We just

 * what we need around the interconnect target module registers.

 * within the interconnect target module range. For example, SGX has

 * them at offset 0x1fc00 in the 32MB module address space. And cpsw

 * has them at offset 0x1200 in the CPSW_WR child. Usually the

 * the interconnect target module registers are at the beginning of

 * the module range though.
