armv7R: K3: am654: Add support for triggering ddr init from SPL
In SPL, DDR should be made available by the end of board_init_f() so that apis in board_init_r() can use ddr. Adding support for triggering DDR initialization from board_init_f(). Reviewed-by: Tom Rini <trini@konsulko.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
