[v4,0/3] iio: acpi_als: Add sotfware trigger support

Message

Some devices (chromebooks) present the ACPI ALS device but do not have
ability to notify when a new sample is present.
Add support for software trigger (hrtimer/sysfs-trigger) to allow
retrieving samples using iio buffers.

The first path fully adds timestamp channel, the second adds a local
variable in probe routine and the last one adds trigger support.

This patch assumes the patch "iio: set default trig->dev.parent" is
applied.
