When fit image boots from ram, the payload will
be prepared in the address of SPL_LOAD_FIT_ADDRESS.
In spl fit generic flow, it will malloc another
memory address and copy whole fit image to this
malloc address. But it is un-necessary for booting
from RAM.
This patch improves this flow by declare the
board_spl_fit_buffer_addr() to replace the original one.
The larger image size (eq: Kernel Image 10~20MB), it
can save more booting time.
