of/fdt: Populate phys_initrd_start/phys_initrd_size from FDT
Now that we have central and global variables holding the physical address and size of the initrd, we can have early_init_dt_check_for_initrd() populate phys_initrd_start/phys_initrd_size for us. This allows us to remove a chunk of code from arch/arm/mm/init.c introduced with commit 65939301acdb ("arm: set initrd_start/initrd_end for fdt scan").
