Subject: [PATCH v5 1/7] irq/irq_sim: add irq_set_type() callback

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

Implement the irq_set_type() callback and call irqd_set_trigger_type()
internally so that users interested in the configured trigger type can
later retrieve it using irqd_get_trigger_type().
