    realtek: Do not set KERNEL_ENTRY just to avoid NO_EXCEPT_FILL
    
    It seems like we are offsetting the KERNEL_ENTRY to +0x400, which is
    also accomplished by the NO_EXCEPT_FILL configuration option.
    
    Since this is the default for MIPS_GENERIC_KERNEL, lets push a little
    bit closer to that one by doing the same thing.
