[PATCH AUTOSEL 5.5 35/35] i2c: pca-platform: Use platform_irq_get_optional

[Sasha Levin]

From: Chris Packham <chris.packham@xxxxxxxxxxxxxxxxxxx>

[ Upstream commit 14c1fe699cad9cb0acda4559c584f136d18fea50 ]

The interrupt is not required so use platform_irq_get_optional() to
avoid error messages like

  i2c-pca-platform 22080000.i2c: IRQ index 0 not found
