Subject: [PATCH 2/2] iio: adc: Fix bad GENMASK use, typos, whitespace

Commit 7906dd52c5a0 ("iio: ina2xx: Fix whitespace and re-order code")
changed the register number of the MASK_ENABLE register from 0x06 to the
value equivalent GENMASK(2,1), although its no mask.
Also fix a typo (INA2_6_6 instead of INA2_2_6), and use the datasheet
name ("Mask/Enable") for the register number define.
Fix bad indentation for channel attributes.
