Subject: ASoC: simple-card: Fix misleading error message

From: Julian Scheel <julian@jusst.de>

commit 7ac45d1635a4cd2e99a4b11903d4a2815ca1b27b upstream.

In case cpu could not be found the error message would always refer to
/codec/ not being found in DT. Fix this by catching the cpu node not found
case explicitly.
