ARM: dts: imx53-qsb: disable 1.2GHz OPP
[ Upstream commit eea96566c189c77e5272585984eb2729881a2f1d ]
The maximum CPU frequency for the i.MX53 QSB is 1GHz, so disable the
1.2GHz OPP. This makes the board work again with configs that have
cpufreq enabled like imx_v6_v7_defconfig on which the board stopped
working with the addition of cpufreq-dt support.
