soundwire: bus: Fix race on the creation of the IRQ domain

[ Upstream commit fd15594b ]

The SoundWire IRQ domain needs to be created before any slaves are added
to the bus, such that the domain is always available when needed. Move
the call to sdw_irq_create() before the calls to sdw_acpi_find_slaves()
and sdw_of_find_slaves().
