    bcm4908: enable Netgear R8000P bootloader image
    
    This enables building BCM4908 "raw" image that can be flashed using
    bootloader web UI. It requires serial console access & stopping booting
    by the "Press any key to stop auto run".
    
    It's easy to build vendor like CHK image but it can't be safely flashed
    using vendor UI at this point. Netgear implements method called "NAND
    incremental flashing" that doesn't seem to flash bootfs partition as
    provided.
    
    Above method seems to update vmlinux.lz without updating 94908.dtb. It
    prevents OpenWrt kernel from booting due to incomplete DTB file. Full
    Netgear R8000P support can be enabled after finding a way to make vendor
    firmware flash OpenWrt firmware including the 94908.dtb update.
