Add a new 'snps,global-regs-starting-offset' DT to dwc3 core to remap the global register start address The RTK DHC SoCs were designed the global register address offset at 0x8100. The default address is at DWC3_GLOBALS_REGS_START (0xc100). Therefore, add the property of device-tree to adjust this start address.
