    x86: make i915 as a kmod with required firmware
    
    i915 driver requires to load correct firmware to work on latest x86
    GPU, it is more reasonable to make it as a kernel module, so that
    initramfs is not required, and it can also save some space from the
    kernel image comparing being a built-in driver
