when dwc3_readl() read register and dwc3_writel() write register, it will run operation 'base + offset - DWC3_GLOBALS_REGS_START' to calculate register address, seem the minus operation can avoid. the original register definition is offset from XHCI base 0x0, now change it to offset from DWC3_GLOBALS_REGS_START(0xc100).
