cirrus: cs89x0: fix the return value handle and remove redundant dev_warn() for platform_get_irq()
There is no possible for platform_get_irq() to return 0 and the return value of platform_get_irq() is more sensible to show the error reason. And there is no need to call the dev_warn() function directly to print a custom message when handling an error from platform_get_irq() function as it is going to display an appropriate error message in case of a failure.
