mb/google/eve: Set DSP SPI clock to 12MHz

To enable faster download of hotword data set the SPI clock to the
Realtek 5514 DSP chip to 12MHz instead of the default 1MHz.

BUG=b:67763576, b:66161281
TEST=cras_test_client --listen /tmp/rec.raw, trigger hotword, and check
the samples using hexdump or cras_test_client --playback_f /tmp/rec.raw
