imx: initialize and use generic timer on i.MX 6UL/ULL
The i.MX 6UL/ULL feature a Cortex-A7 CPU which suppor the ARM
generic timer. This change makes use of the ARM generic timer in
U-Boot.
This is crucial to make the ARM generic timers usable in Linux since
timer_init() initalizes the system counter module, which is necessary
to use the generic timers CP15 registers.
