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.
