cirrus: cs89x0: fix the return value handle and remove redundant dev_warn() for platform_get_irq()

Browse source

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.
