[PATCH v2] i2c: designware: Suppress error message if platform_get_irq() < 0

[Alexey Brodkin <Alexey.Brodkin-HKixBCOQz3hWk0Htik3J/w@public.gmane.org>]

As discussed here https://lkml.org/lkml/2015/3/3/568 and here
https://lkml.org/lkml/2015/3/3/453 we're looking forward for
implementing warnings and errors outputs right in platform_get_irq()
instead of having all kind of different outputs in each and every driver
that uses platform_get_irq().
