Subject: [RESEND][PATCH] iio: simplify with regmap_set_bits(), regmap_clear_bits()

Simplify the way regmap is accessed in iio drivers.

Instead of using regmap_update_bits() and passing the mask twice, use
regmap_set_bits().

Instead of using regmap_update_bits() and passing val = 0, use
regmap_clear_bits().

I found five more drivers below drivers/iio that could benefit from such
a conversion:

drivers/iio/adc/ad7173.c | 2 +-
drivers/iio/adc/ti-ads1298.c | 13 ++++++-------

But even without addressing these:
