[PATCH 2/2] i2c: mv64xxx: propagate the return value of platform_get_irq()

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

platform_get_irq() returns an error code, so instead of inventing our
own error code (-ENXIO), return the one provided by
platform_get_irq(). Most notably, this allows an -EPROBE_DEFER
returned by platform_get_irq() to be propagate as the return value of
->probe(), which allows deferred probing of the interrupt controller.
