i2c: smbus: remove outdated references to irq level triggers
IRQ levels are now handled within the IRQ core. Remove the forgotten references from the documentation. Fixes: 9b9f2b8bc2ac ("i2c: i2c-smbus: Use threaded irq for smbalert") Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Reviewed-by: Luca Ceresoli <luca@lucaceresoli.net> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

* Handling can be done either through our IRQ handler, or by the
* adapter (from its handler, periodic polling, or whatever).
*
- * NOTE that if we manage the IRQ, we *MUST* know if it's level or
- * edge triggered in order to hand it to the workqueue correctly.
- * If triggering the alert seems to wedge the system, you probably
- * should have said it's level triggered.
- *
* This returns the ara client, which should be saved for later use with
* i2c_handle_smbus_alert() and ultimately i2c_unregister_device(); or an
* ERRPTR to indicate an error.
