i2c: s3c2410: fix IRQ check

Browse Source 
[ Upstream commit d6840a5e37 ]

Iff platform_get_irq() returns 0, the driver's probe() method will return 0
early (as if the method's call was successful).  Let's consider IRQ0 valid
for simplicity -- devm_request_irq() can always override that decision...
