Patrick Delaunay ac5769cba1 stm32mp1: remove fdt_high and initrd_high in environment 
Remove fdt_high and initrd_high (set to 0xffffffff) in stm32mp1 board
enviromnent, and U-Boot always relocate FDT and initrd in bootm command.

This relocation is limited by CONFIG_SYS_BOOTMAPSZ which indicates
the size of the memory region where it is safe to place data passed
to the Linux kernel (DTB, initrd), it is
a) Less than or equal to RAM size.
b) not within the kernel's highmem region

So 256M seems large enough in most circumstances and users
can override this value via environment variable "bootm_mapsize"
if needed.

This modification increases the boot time but avoid assumption
on aligned address for bootm command.

A user can still define this variables themselves if the FDT or
initrd is either left in-place or copied to a specific location.
