ENGR00175117 [MX6DL LPDDR2 Board] Apply Initializtion script and enable U-Boot

Apply script "Mx6DL_init_LPDDR2_400MHz_Micron_1.1.inc" in IVT, make U-boot
work for the LPDDR2 Board. The Make target name for the new board is
"MX6DL_ARM2_LPDDR2_CONFIG"

The script is provided by Chen Wei - B26879 for a quick bring up, which don't
have a corresponding compass link. It is uploaded to CR ticket page for
reference.

Originally for MX6DL DDR3 board, "CONFIG_MX6DL" is defined. It is used by
"board/freescale/mx6q_arm2/flash_header.S" to select the correct IVT. Since
MX6DL LPDDR2 board also define this macro, for distiguish purpose, another
2 macros "CONFIG_MX6DL_DDR3", "CONFIG_MX6DL_LDPPR2" are defined
