[PATCH 3/4] soundwire: bus_type: Create IRQ mapping before calling driver probe()

[Richard Fitzgerald]

Call sdw_irq_create_mapping() before calling the peripheral driver
probe() so that it is possible to request the IRQ during probe().

Previously creation of the mapping was conditional on the use_domain_irq
flag in the driver properties. But these are filled in after probe(),
which meant it wasn't possible to request the IRQ during probe(). This
was ok for MFD drivers where only children requested the IRQ. But for
normal drivers it led to the non-standard behavior of having to defer
requesting the IRQ until after probe().
