[PATCH 1/7] ARM: imx: add timer stop flag to ARM power off state

[Stefan Agner]

When the CPU is in ARM power off state the ARM architected
timers are stopped. The flag is already present in the higher
power WAIT mode.

This allows to use the ARM generic timer on i.MX 6UL/6ULL SoC.
Without the flag the kernel freezes when the timer enters the
first time ARM power off mode.
