imx7d-colibri: limit to 800 mhz and 1 ghz operating points
Copy operating points from imx7d.dtsi removing unsupported 1.2 ghz one. This fixes the following run time error: [ 2.002793] DCDC2: unsupportable voltage range: 1225000-1100000uV [ 2.010618] DCDC2: unsupportable voltage range: 1225000-1100000uV [ 2.018391] cpu cpu0: failed to scale vddarm up: -22 [ 2.025083] cpufreq: __target_index: Failed to change cpu frequency: -22 Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Acked-by: Dominik Sliwa <dominik.sliwa@toradex.com>
