powerpc/lib/board.c: Call run_post(POST_ROM) before relocating

Browse source 
The call to run_post(POST_ROM) which can run the POST memory test
is currently called too late when gd has already been copied to DRAM.

This results in failure to boot Linux after a POST_ROM memory test
tested all RAM while gd was already relocated to DRAM due to gd being
overwritten by the POST_ROM memory test.

Support this by moving the call to run_post(POST_ROM) to run earlier,
before U-Boot has started to move data to DRAM (from late board_init_f
to early board_init_f) where DRAM is initialized, but not used yet.

This allows that an POST memory test can test the whole DRAM,
including the area where the board info struct is located.
