Subject: i2c: synquacer: fix deferred probing

Git-commit: 8d744da241b81f4211f4813b0d3c1981326fa9ca
Patch-mainline: v5.15-rc1
References: git-fixes

The driver overrides the error codes returned by platform_get_irq() to
-ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the
error codes upstream.

Fixes: 0d676a6c4390 ("i2c: add support for Socionext SynQuacer I2C controller")
