Martin Blumenstingl 827df0571f iio: adc: meson-saradc: use the address attribute from iio_chan_spec 
Until now the "channel" number is identical to how the channel is
identified inside the (FIFO) registers. In our case we have eight
channels and the hardware also has eight inputs.

However, there are two special inputs:
- channel 6 can select between the SAR_ADC_CH6 pad and the chip's
  internal temperature sensor
- channel 7 can select between SAR_ADC_CH7 and VSS, VDD / 4, VDD / 2,
  VDD * 3 / 4 and VDD.

When programming the registers to read for example the temperature
sensor we have to select FIFO channel 6, set the correct bit which muxes
channel 6 to the temperature sensor and then start the ADC measurement
for channel 6 as usual.

When we add support for the temperature sensor the driver has to know
about that it has to use FIFO channel 6 to measure using the chip's
internal temperature sensor. However, in that case the iio_chan_spec
channel will not be 6 because this is already used for the SAR_ADC_CH6
pad input. Thus we use iio_chan_spec's address field to store the FIFO
channel number for each channel.
