ec/google/chromeec: Demote LPC EC error printk from ERR to SPEW
Several EC host commands check for support of a given feature or msg
version, and a non-zero response does not necessarily indicate an actual
error. Since the caller is (should be) handling the non-zero response to
the host command, demote the EC printk from ERR to SPEW to clean up the
console log and prevent non-errors from causing false failures in
firmware tests.
