i2c: synquacer: fix deferred probing
[ Upstream commit 8d744da241b81f4211f4813b0d3c1981326fa9ca ]
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.
