iio: cros: unify hw fifo attributes without API changes
Commit 2e2366c2d141 ("iio: cros_ec: unify hw fifo attributes into the core file") should be reverted as it set buffer extended attributes at the wrong place. However, to revert it will requires to revert more commits: commit 165aea80e2e2 ("iio: cros_ec: use devm_iio_triggered_buffer_setup_ext()") commit 21232b4456ba ("iio: buffer: remove iio_buffer_set_attrs() helper")). and we would still have conflict with more recent development. commit ee708e6baacd ("iio: buffer: introduce support for attaching more IIO buffers") Instead, this commit reverts the first 2 commits without re-adding iio_buffer_set_attrs() and set the buffer extended attributes at the right place: 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 when EC does not support FIFO, as there is no FIFO to manage. 3. Use devm_iio_triggered_buffer_setup_ext() when EC has a FIFO to specify the buffer extended attributes.
