ath79: image: fix initramfs for safeloader devices

Browse Source 
Currently it's not possible to tftpboot initramfs image on archer-c7-v5
as the image contains tplink-v1-header which leads to:

 ath> bootm
 ## Booting image at 81000000 ...
 Bad Magic Number

as U-Boot expects uImage wrapped image. This is caused by following
inheritance issue:

  define Device/Init
    KERNEL_INITRAMFS = $$(KERNEL)

  define Device/tplink-v1
    KERNEL := kernel-bin | append-dtb | lzma
    KERNEL_INITRAMFS := kernel-bin | append-dtb | lzma | tplink-v1-header

  define Device/tplink-safeloader
    $(Device/tplink-v1)

  define Device/tplink-safeloader-uimage
    $(Device/tplink-safeloader)
    KERNEL := kernel-bin | append-dtb | lzma | uImageArcher lzma

  define Device/tplink_archer-c7-v5
    $(Device/tplink-safeloader-uimage)

where tplink-v1 defines KERNEL_INITRAMFS with tplink-v1-header and it's
then used by all devices inheriting from tplink-safeloader. Fix this by
overriding KERNEL_INITRAMFS to KERNEL variable again.
