Kirkwood: dram_init is moved to dram.c
For all Kirkwood boards so far dram_init function is duplicated dram_init function is moved to dram.c and relevant code from all board specific files removed If any board needs specific dram init handling than standard one, then, a macro CONFIG_SYS_BOARD_DRAM_INIT should be defined in board config header file and the dram_init function can be put in board specific source file For ex. keymile boards Signed-off-by: Prafulla Wadaskar <prafulla@marvell.com>
