Subject: [PATCH 01/23] irqdomain: Introduce irq_domain_free()
Date: Fri, 14 Jun 2024 19:32:02 +0200

In preparation of the introduction of the irq domain instantiation,
introduce irq_domain_free() to avoid code duplication on later
modifications.

This new function is an extraction of the current operations performed
to free the irq domain. No functional changes are introduced.
