Revert "Revert "RK patch for improve usb camera performance""

We revert this patch previously is because Tinker can't recognize usb device after apply this patch.
Now, we have clarified that this is because we only bring 1 CPU core up.
So we apply this patch again after we solved the CPU core issue

This reverts commit 2e432c3.
