ARM: imx: add i.mx6ulz msl support
The i.MX 6ULZ processor is a high-performance, ultra cost-efficient consumer Linux processor featuring an advanced implementation of a single Arm® Cortex®-A7 core, which operates at speeds up to 900 MHz. This patch adds basic MSL support for i.MX6ULZ, the i.MX6ULZ has same soc_id as i.MX6ULL, and SRC_SBMR2 bit[6] is to differentiate i.MX6ULZ from i.MX6ULL, 1'b1 means i.MX6ULZ and 1'b0 means i.MX6ULL.
