platform: generic: Pass FDT to early/final_init overrides

Several of these override functions access the FDT blob. Explicitly
indicate which callbacks are allowed to modify the FDT blob by passing
the parameter as a possibly-const pointer. This also reduces code size
by deduplicating the call to fdt_get_address().
