[PATCH v1] soc: qcom: apr: Drop unused apr_device_id

["Uwe Kleine-König (The Capable Hub)" <u.kleine-koenig@baylibre.com>]

apr_device_id was introduced in commit 6adba21eb434 ("soc: qcom: Add APR
bus driver") in 2018, and since then not a single driver made use of it.

So drop the unused id_table pointer from struct apr_driver and move
APR_NAME_SIZE to the apr header which still has a usage of it.

Note that with the id_table being NULL apr_device_match() degrades to just
of_driver_match_device(), so replace this callback accordingly.
