Subject: [PATCH] of: unittest: Use platform_get_irq_optional() for non-existing interrupt

As platform_get_irq() now prints an error when the interrupt
does not exist, a scary warning may be printed for a non-existing
interrupt:

    platform testcase-data:testcase-device2: IRQ index 0 not found

Fix this by calling platform_get_irq_optional() instead.

Fixes: 7723f4c5ecdb8d83 ("driver core: platform: Add an error message to platform_get_irq*()")
Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>

This is a fix for v5.4.
