[Marvell-armhf] Setting u-boot ftd_high to resolve kernel hung (#10204)

Browse Source 
Why I did it
Kernel hang in during early boot is caused due overwriting of device tree with uncompressing kernel. Added the fdt_high which gives a safe offset from kernel location.

How I did it
Setting uboot environment variable fdt_high.

How to verify it
Successful boot of bullseye kernel on Marvell Armada 380/385.
