Upon Diag function bind, the DLOAD memory region should be updated with the USB PID and serial number in order to support a persistent connection with the PC if the device reboots into download mode. This functionality need not be handled in the android.c driver. The only reason it is there is to be able to locate the IO address which is specified in device tree. Since this can be done from the Diag function driver directly, move the handling there. The address itself can be specified under the "qcom,msm-imem" parent with its own "qcom,msm-imem-diag-dload" compatible string. For now, allow falling back to retrieving the address from the "android_usb" for backwards compatibility until the device tree files are updated.
