remoteproc: imx_dsp_rproc: Wait for suspend ACK only if WAIT_FW_CONFIRMATION is set
The DSP suspend path currently waits unconditionally for a suspend ack
from the firmware. This breaks firmwares that do not implement the
mailbox-based CONFIRMATION handshake, as the DSP never responds and
system suspend fails with -EBUSY.
The driver already uses the WAIT_FW_CONFIRMATION flag to indicate that
the firmware supports the CONFIRMATION handshake at boot. Apply the same
logic during suspend: only send the suspend message and wait for the
suspend ack when the firmware is expected to support it.
