When the kernel is configured to use the Thumb-2 instruction set "suspend-to-memory" fails to resume. Observed on a Colibri iMX6ULL (i.MX 6ULL) and Apalis iMX6 (i.MX 6Q).
It looks like the CPU resumes unconditionally in ARM instruction mode and then chokes on the presented Thumb-2 code it should execute.
Fix this by using the arm instruction set for all code in suspend-imx6.S.
