of/fdt: Populate phys_initrd_start/phys_initrd_size from FDT

Browse Source 
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 65939301ac ("arm: set initrd_start/initrd_end
for fdt scan").
