iio: adc: spear_adc: mask SPEAR_ADC_STATUS channel and avg sample before setting register

Browse source

[ Upstream commit d75c7021c0 ]

avg sample info is a bit field coded inside the following
bits: 5,6,7 and 8 of a device status register.

Channel num info the same, but over bits: 1, 2 and 3.

Mask both values in order to avoid touching other register bits,
since the first info (avg sample), came from DT.
