    airoha: adjust and default the loadaddr
    
    Similar to e92b153e99 ("mediatek: introduce KERNEL_LOADADDR to Device/Default template"),
    let's move the default loadaddr to Device/Default.
    
    What's more, use 0x80200000 instead of the SDK default value 0x80088000
    to avoid the following error which may overwrite TZ memory and cause crash:
    
        [    0.000000] [Firmware Bug]: Kernel image misaligned at boot, please fix your bootloader!
        [    0.000000] OF: reserved mem: Reserved memory: failed to reserve memory for node 'atf at 80000000': base 0x0000000080000000, size 2 MiB
