ARM: dts: imx6ull-colibri: use pull-down for adc pins
Disable the keeper and enable a 100k pull-down on the ADC pins as per
the following note in section 13.2 of the i.MX 6ULL Application
Processor Reference Manual, Rev. 1, 11/2017 [1]:
The keeper causes an undesired jump behavior in ADC. To avoid the
problem, disable keeper before starting ADC.
