ARM: imx: Add basic msl support for imx6sll
Add basic MSL support for i.MX6SLL. The i.MX 6SoloLiteLite application processors are NXP's latest additions to a growing family of multimedia-focused products offering high-performance processing optimized for lowest power consumption. The i.MX 6SoloLiteLite processors feature NXP's advanced implementation of the ARM Cortex-A9 core, which can be interfaced with LPDDR3 and LPDDR2 DRAM memory devices.
