ASoC: imx-pcm-rpmsg: Flush pending work in hw_free

imx_rpmsg_terminate_all() queues the TERMINATE message to the workqueue
and returns, while the DAI hw_free() synchronously gates the audio
clock. The two can then run concurrently, and this concurrent access to
the shared audio clock path can cause a stop failure or even hang the
system.

Flush the workqueue in a new component hw_free(), which runs before the
DAI hw_free(), so TERMINATE is fully handled before the clock is gated.
CLOSE stays the last message.
