This patch set adds i.MX6ULZ SoC support, i.MX6ULZ is a new SoC of
i.MX6 family, compared to i.MX6ULL, it removes below modules:
- UART5/UART6/UART7/UART8;
- PWM5/PWM6/PWM7/PWM8;

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
