    mediatek: introduce KERNEL_LOADADDR to Device/Default template
    
    We need to reset KERNEL_LOADADDR if we use it on a per-device base.
    Otherwise the previous value will be kept in case a device doesn't
    define KERNEL_LOADADDR and relies on the default.
    
    Move initializing KERNEL_LOADADDR to target/linux/mediatek/image/Makefile,
    similar to how it's done also on the ramips target.
    
    This fixes image size related breakage on devices which rely on the
    default value of KERNEL_LOADADDR.
    
    While at it use 0x48000000 which is more common than the previous default
    0x44000000 for the filogic subtarget.
    
    Fixed: e7c399bee6 ("filogic: add support for ASUS TUF-AX4200")
