Update the ddr scripts for LPDDR2 and add two build configs for LPDDR2
arm2 board. Since the LPDDR2 arm2 board has different DDR size, use
CONFIG_DDR_MB in defconfig to replace the PHYS_SDRAM_SIZE.

This patch adds the i.MX6DL arm2 board support. The i.MX6DL ARM2
shared the same board with i.MX6Q ARM2 board since the i.MX6DL is
pin-pin compatible with i.MX6Q.
The patch also support the DDR 32-BIT mode option. Please define
CONFIG_DDR_32BIT in the board configure file to enable DDR 32-BIT
mode.But due to the board design, it's 64bit DDR buswidth physically,
so, if you CONFIG_DDR_32BIT, the DDR memory size will be half of it.
