[PATCH v1] ASoC: rt5640: Silence warning message about missing interrupt

[Dmitry Osipenko <digetx@gmail.com>]

Interrupt is optional for the RT5640 codec. Nexus 7 doesn't use interrupt,
this results in a noisy warning message that looks like a error condition.
Make interrupt explicitly optional to silence the message, use modern
IRQF_NO_AUTOEN flag and correct the reg[q]uest typo in the message.
