Delete kernel debug related parameter for performance
Those deleted kernel parameters are extremely heavy debug. The boot process is rather slow on machines which has a complicate motherboard and lots of pci devices(Lenovo RD640). The debug process costs so much resouce, evetually it will impact normal functions, such as cpus are so busy dealing with debug info in kernelspace, they do not have time to reponse udev event in userspace and failed to bring up pci devices.
