        fadump: do not use squash to reduce image size
    
        With commit fa9201b2 ("fadump: isolate fadump initramfs image within
        the default one"), initramfs image gets to hold two squash images, one
        for production kernel boot purpose and the other for capture kernel
        boot. Having separate images improved reliability for both production
        kernel and capture kernel boot scenarios, but the size of initramfs
        image became considerably larger.
    
        Instead of having squash images, compressing $initdir without using
        squash images reduced the size of initramfs image for fadump case by
        around 30%. So, avoid using squash for fadump case.
