Referring to platform_get_irq()'s definition, the return value has
already been checked if ret < 0, and printed via dev_err_probe().
Calling dev_err_probe() one more time outside platform_get_irq()
is obviously redundant. Removing outside dev_err_probe() to
clean it up.
Besides, switch to use platform_get_irq_optional() since the irq
is optional here.
