fixes commit 2e2366c2d141 ("iio: cros_ec: unify hw fifo attributes into the core file")
fixes commit 165aea80e2e2 ("iio: cros_ec: use devm_iio_triggered_buffer_setup_ext()")
1. Instead of adding has_fw_fifo, deduct it from the configuration:
- EC must support FIFO (EC_FEATURE_MOTION_SENSE_FIFO) set.
- sensors send data a regular interval (accelerometer, gyro,
magnetomer, barometer, light sensor).
- "Legacy accelerometer" is only present on EC without FIFO, so we don't
need to set buffer attributes.
2. devm_iio_triggered_buffer_setup_ext() does not need to be called.
Only when the EC support FIFO we set the buffer attributes directly to set
timeout and watermark.
