[PATCH] irqdomain: Export __irq_domain_alloc_irqs() to modules

[Marc Zyngier <maz@kernel.org>]

The Apple PCIe controller driver allocates interrupts generated
by the PCIe ports, and uses irq_domain_alloc_irqs() for that.
THis is an inline function that uses __irq_domain_alloc_irqs()
as a backend.

Since the driver can be built as a module, __irq_domain_alloc_irqs()
must be exported.

Fixes: 201adeaa9d82 ("PCI: apple: Add INTx and per-port interrupt support")
Signed-off-by: Marc Zyngier <maz@kernel.org>

Notes:
    Since the offending code is only in the PCI tree so far,
    it would make sense if Lorenzo could take this patch directly.
