iio: adc: vf610: use sample period of minimum 6 ADC clocksColibri_VF_LinuxImageV2.3Beta7_20150203toradex_vf_3.18
The patch changes the sample period to 6 ADC clocks instead of the earlier 2 ADC clocks. This is required as reading multiple channels simultaneously at short time intervals (< 10ms) leads to fluctuations in the internal temperature sensor readouts. Internal temperature sensor seems to require atleast 4 ADC clocks for a stable reading. Also change the formula for calculating available sampling frequencies accordingly.
