ARM: sunxi: dts: pangolin: disable 1.2Ghz cpufreq
disable the 1.2Ghz frequency point so users have to enable it explicity. this should ensure that only boards with installed thermal solutions are used with 1.2Ghz. Note that running on 1.2Ghz will not damage the board as we turn CPU off when overheating. We only want to avoid unexpected shutdowns for users when using the default setup and not mounting the heat sink. Signed-off-by: Klaus Goger <klaus.goger@theobroma-systems.com>
