iio: adc: ad7124: reduce the number of SPI transfers
The ad7124_init_config_vref() function writes the AD7124_ADC_CONTROL
register for each channel that is configured to use the internal
reference.
The ad7124_write_config()function performs 7 SPI transfers for
configuring 2 registers: config_x and filter_x.
Reduce the number of SPI transfers:
-during the probe by only setting the st->adc_control value in
ad7124_init_config_vref() and writing to the device only at the end of
ad7124_setup().
-in ad7124_write_config() by grouping writes to the same register.
