Below are codes for accessing usb sysif_regs in driver:
usb_sys_regs = (struct usb_sys_interface *)
((u32)dr_regs + USB_DR_SYS_OFFSET);
these codes work in 32-bit, but in 64-bit, use u32 to type cast the address
of ioremap is not right, and accessing members of 'usb_sys_regs' will cause
call trace, so use unsigned long for both 32-bit and 64-bit.
