Subject: [PATCH 2/4] ASoC: SOF: imx8: Add ops for i.MX8QM

From: Paul Olaru <paul.olaru@....com>

i.MX8QM and i.MX8QXP are mostly identical platforms with minor hardware
differences. One of these differences affects the firmware boot process,
requiring the run operation to differ. All other ops are reused.
