[PATCH v4 0/2] iio: light: add support for APDS9660 sensor

This patchset adds support for the APDS9960 ALS + proximity + gesture
sensor.

Included support for the various adjustable settings and controls:
 * Falling and rising ALS + proximity thresholds events
 * Gain controls
 * ALS time integration

Changes from v3:
 * Added interrupt client mode document reference in DT bindings
 * Add missing dep for CONFIG_REGMAP_I2C in respective Kconfig
 * Changed from iio_trigger_poll_chained() to irq_work queue
 * Changed channel masks to prevent channels that can't be polled from
   having sysfs entries
 * Renamed regmap_field declarations with apds9660_* prefix 
 * Added available channel masks and removed unneeded buffer copy in
   poll function
 * Remove unneeded default regmap values in apds9960_reg_defaults 
 * Clear interrupts from ALS and proximity sensor seperately to avoid
   race condition
 * Changed max threshold values to a macro define, and prevent values
   less than 0
 * Avoid needlessly checking the APDS9960_REG_GFLVL value until we read
   all the FIFO from the count value. Note this can save up to 32 
   superfluous i2c reads per gesture engine entry
