common: move ram_base calculation to independent INITCALL()

Browse Source 
Currently, ram_base is calculated within setup_dest_addr().
However, upcoming patches that enable U-Boot relocation to the highest
DRAM bank require ram_base to be initialized earlier.

The default dram_init_banksize() definition relies on ram_base
to calculate the start of the first bank. But following patches
will move that function to execute immediately before setup_dest_addr().

So let's split the ram_base initialization in its own INITCALL.
