Eric Auger a01d3abe87 vfio: platform: Switch to platform_get_irq_optional() 
commit 723fe298ad85ad1278bd2312469ad14738953cc6 upstream.

Since commit 7723f4c5ecdb ("driver core: platform: Add an error
message to platform_get_irq*()"), platform_get_irq() calls dev_err()
on an error. As we enumerate all interrupts until platform_get_irq()
fails, we now systematically get a message such as:
"vfio-platform fff51000.ethernet: IRQ index 3 not found" which is
a false positive.

Let's use platform_get_irq_optional() instead.
