Andy Shevchenko 81eeb2f577 ACPI: utils: Document for_each_acpi_dev_match() macro 
The macro requires to call acpi_dev_put() on each iteration.
Due to this it doesn't tolerate sudden disappearence of the devices.

Document all these nuances to prevent users blindly call it without
understanding the possible issues.

While at it, add the note to the acpi_dev_get_next_match_dev() and
advertise acpi_dev_put() instead of put_device() in the whole family
of the helper functions.

Fixes: bf263f64e8 ("media: ACPI / bus: Add acpi_dev_get_next_match_dev() and helper macro")
