ENGR00181337-3 i.mx6: i.mx6sl: add initial support for i.mx6sl ARM2 board

This patch is to add the initial support for i.mx6sl ARM2 board, the patch does:
	- implemention of LPDDR2 init script
	- Plug-in/DCD mode support to do DDR initialization
	- Debug UART(UART1) support
	- SPI-NOR(M25P32, 4MB) flash support
	- FEC support, PHY(LAN8720A, RMII mode)
	- SD/MMC card support, SD1/SD2/SD3
